Mozilla Firefox is a free and open source[12] web browser developed for Microsoft Windows, Mac OS X, and Linux
coordinated by Mozilla Corporation and Mozilla Foundation. Firefox uses the Gecko layout engine to render web
pages, which implements current and anticipated web standards.[13] As of July 2012, Firefox has approximately 24%
of worldwide usage share of web browsers, making it the third most widely used web browser.[14][15][16] The
browser has had particular success in Indonesia, Germany and Poland, where it is the most popular browser with
66%,[17] 48%[18] and 47%[19] of the market share respectively.

Firefox 2

History
The Firefox project began as an experimental branch of the Mozilla project by Dave Hyatt, Joe Hewitt and Blake
Ross. They believed the commercial requirements of Netscape's sponsorship and developer-driven feature creep
compromised the utility of the Mozilla browser.[20] To combat what they saw as the Mozilla Suite's software bloat,
they created a stand-alone browser, with which they intended to replace the Mozilla Suite. On April 3, 2003, the
Mozilla Organization announced that they planned to change their focus from the Mozilla Suite to Firefox and
Thunderbird.[21]
The Firefox project has undergone several name changes. Originally titled Phoenix, it was renamed because of
trademark problems with Phoenix Technologies. The replacement name, Firebird, provoked an intense response
from the Firebird free database software project.[22][23] In response, the Mozilla Foundation stated that the browser
should always bear the name Mozilla Firebird to avoid confusion with the database software. After further pressure
from the database server's development community, on February 9, 2004, Mozilla Firebird became Mozilla
Firefox,[24] often referred to as simply Firefox. Mozilla prefers that Firefox be abbreviated as Fx or fx, though it is
often abbreviated as FF.[25] The Firefox project went through many versions before version 1.0 was released on
November 9, 2004.

Features
Features include tabbed browsing, spell checking, incremental find, live bookmarking, smart bookmarks, a download
manager, private browsing, location-aware browsing (also known as "geolocation") based on a Google service[26]
and an integrated search system that uses Google by default in most localizations. Functions can be added through
extensions, created by third-party developers,[27] of which there is a wide selection, a feature that has attracted many
of Firefox's users.
Additionally, Firefox provides an environment for web developers in which they can use built-in tools, such as the
Error Console or the DOM Inspector, or extensions, such as Firebug.

Standards
Firefox implements many web standards,
including HTML4 (partial HTML5), XML,
XHTML, MathML, SVG 1.1 (partial),[28]
CSS (with extensions),[29] ECMAScript
(JavaScript), DOM, XSLT, XPath, and
APNG (Animated PNG) images with alpha
transparency.[30] Firefox also implements
standards proposals created by the
WHATWG such as client-side
storage,[31][32] and canvas element.[33]

Firefox has passed the Acid2
standards-compliance test since version
3.0.[34] Mozilla had originally stated that The results of the Acid3 test (as of September 2011) on Firefox 7.0
they did not intend for Firefox to pass the
Acid3 test fully because they believed that the SVG fonts part of the test had become outdated and irrelevant, due to
WOFF being agreed upon as a standard by all major browser makers.[35] Because the SVG font tests were removed
from the Acid3 test in September 2011, Firefox 4 and greater scored 100/100.[36][37]

Firefox also implements[38] a proprietary protocol[39] from Google called "safebrowsing" (used to exchange data
related with "phishing and malware protection").

Firefox 3

Security
Firefox uses a sandbox security model,[40] and limits scripts from accessing data from other web sites based on the
same origin policy.[41] It uses SSL/TLS to protect communications with web servers using strong cryptography when
using the HTTPS protocol.[42] It also provides support for web applications to use smartcards for authentication
purposes.[43]
The Mozilla Foundation offers a "bug bounty" (up to 3000 USD cash reward and a Mozilla T-shirt) to researchers
who discover severe security holes in Firefox.[44] Official guidelines for handling security vulnerabilities discourage
early disclosure of vulnerabilities so as not to give potential attackers an advantage in creating exploits.[45]
Because Firefox generally has fewer publicly known unpatched security vulnerabilities than Internet Explorer (see
Comparison of web browsers), improved security is often cited as a reason to switch from Internet Explorer to
Firefox.[46][47][48][49] The Washington Post reports that exploit code for known, critical unpatched security
vulnerabilities in Internet Explorer was available for 284 days in 2006. In comparison, exploit code for known,
critical security vulnerabilities in Firefox was available for 9 days before Mozilla issued a patch to remedy the
problem.[50]
A 2006 Symantec study showed that, although Firefox had surpassed other browsers in the number of
vendor-confirmed vulnerabilities that year through September, these vulnerabilities were patched far more quickly
than those found in other browsers – Firefox's vulnerabilities were fixed on average one day after the exploit code
was made available, as compared to nine days for Internet Explorer.[51] Symantec later clarified their statement,
saying that Firefox still had fewer security vulnerabilities than Internet Explorer, as counted by security
researchers.[52]
In 2010 a study of the National Institute of Standards and Technology (NIST) based on data compiled from the
National Vulnerability Database (NVD) Firefox was listed as the 5th most vulnerable desktop software. Internet
Explorer ranked only 8th on the list, and Google Chrome as 1st.[53]
InfoWorld has cited security experts saying that as Firefox becomes more popular, more vulnerabilities will be
found,[54] a claim that Mitchell Baker, president of the Mozilla Foundation, has denied: "There is this idea that
market share alone will make you have more vulnerabilities. It is not relational at all."[55]
In October 2009, Microsoft's security engineers acknowledged that Firefox was vulnerable since February of that
year due to a .NET Framework 3.5 SP1 Windows update that silently installed a buggy 'Windows Presentation
Foundation' plug-in into Firefox.[56] This vulnerability has since been patched by Microsoft.[57]
As of February 11, 2011, Firefox 3.6 had no (known) unpatched security vulnerabilities according to Secunia.[58]
Internet Explorer 8 had five unpatched security vulnerabilities, the worst being rated "Less Critical" by Secunia.[59]
Mozilla claims, that all patched vulnerabilities of Mozilla products are publicly listed.[60] However, the corporation
has been caught multiple times fixing vulnerabilities silently or with delayed notice.[61][62][63]

Telemetry
When Firefox is upgraded to version 7.0, an information bar will appear asking users whether they would like to
send performance statistics (also known as “telemetry”) to Mozilla. According to Mozilla's privacy policy,[64] these
statistics are stored only in aggregate format, and the only personally-identifiable information transmitted is the
user's IP address.

Localizations
Firefox is a heavily localized web browser. The first official release in November 2004 was available in 24 different
languages and for 28 locales, including British English/American English, European Spanish/Argentine Spanish and
Chinese in Traditional Chinese characters/Simplified Chinese characters.[65] Currently supported versions 10.0.6 and
14.0.1 are available for 85 locales (76 languages)[66] and 88 locales (78 languages)[9] respectively.

Firefox 4

Licensing
Firefox source code is free software, with most of it being released under the Mozilla Public License (MPL).[10] This
license permits anyone to view, modify, and/or redistribute the source code, and several publicly released
applications have been built on it; for example, Netscape, Flock, Miro, Iceweasel, and Songbird make use of code
from Firefox.
In the past, Firefox was licensed solely under the MPL,[67] which the FSF (Free Software Foundation) criticized for
being weak copyleft; the license permitted, in limited ways, proprietary derivative works. Additionally, code only
licensed under the MPL could not legally be linked with code under the GPL.[68][69] To address these concerns,
Mozilla re-licensed most of Firefox under the tri-license scheme of MPL, GPL, or LGPL. Since the re-licensing,
developers were free to choose the license under which they received most of the code, to suit their intended use:
GPL or LGPL linking and derivative works when one of those licenses is chosen, or MPL use (including the
possibility of proprietary derivative works) if they chose the MPL.[67] However, on January 3, 2012, Mozilla
released the GPL-compatible MPL 2.0,[70] and with the release of Firefox 13 on June 5, 2012, Mozilla used it to
replace the tri-licensing scheme.[71]

Trademark and logo
The name "Mozilla Firefox" is a registered trademark; along with the official Firefox logo, it may only be used under
certain terms and conditions. Anyone may redistribute the official binaries in unmodified form and use the Firefox
name and branding for such distribution, but restrictions are placed on distributions which modify the underlying
source code.[72] The name "Firefox" derives from a nickname of the red panda.[73]
Mozilla has placed the Firefox logo files under open-source licenses,[74][75] but its trademark guidelines do not allow
displaying altered[76] or similar logos[77] in contexts where trademark law applies.
There has been some controversy over the Mozilla Foundation's intentions in
stopping certain open source distributions from using the "Firefox" trademark.[12]
Mozilla Foundation Chairperson Mitchell Baker explained in an interview in 2007
that distributions could freely use the Firefox trademark if they did not modify
source-code, and that the Mozilla Foundation's only concern was with users
getting a consistent experience when they used "Firefox".[78]

To allow distributions of the code without using the official branding, the Firefox
source code contains a "branding switch". This switch allows the code to be
compiled without the official logo and name, for example to produce a derivative Logo used for Iceweasel

work unencumbered by restrictions on the Firefox trademark (this is also often
used for alphas of future Firefox versions). In the unbranded compilation the trademarked logo and name are
replaced with a freely distributable generic globe logo and the name of the release series from which the modified
version was derived.

Distributing modified versions of Firefox under the "Firefox" name requires explicit approval from Mozilla for the
changes made to the underlying code, and requires the use of all of the official branding. For example, it is not
permissible to use the name "Firefox" without also using the official logo. When the Debian project decided to stop
using the official Firefox logo in 2006 (because Mozilla's copyright restrictions at the time were incompatible with
Debian's guidelines), they were told by a representative of the Mozilla Foundation that this was not acceptable, and
were asked either to comply with the published trademark guidelines or cease using the "Firefox" name in their
distribution.[79] Ultimately, Debian switched to branding their modified version of Firefox "Iceweasel", along with
other Mozilla software.

Firefox 5

Branding and visual identity
Early Firebird and Phoenix releases of Firefox were considered to have had reasonable visual designs, but were not
up to the same standards as many professionally released software packages. In October 2003, professional interface
designer Steven Garrity wrote an article covering everything he considered to be wrong with Mozilla's visual
identity.[80] The page received a great deal of attention; the majority of criticism leveled at the article fell along the
lines of "where's the patch?"
Shortly afterwards, Garrity was invited by the Mozilla Foundation to head up the
new visual identity team. The release of Firefox 0.8 in February 2004 saw the
introduction of the new branding efforts, including new icon designs by
silverorange, a group of web developers with a long-standing relationship with
Mozilla, with final renderings by Jon Hicks, who had previously worked on
Camino.[82][83] The logo was later revised and updated, fixing several flaws found
when it was enlarged.[84]

The animal shown in the logo is a stylized fox, although "firefox" is considered to
be a common name for the red panda. The panda, according to Hicks, "didn't really Blue globe artwork is distributed
with Firefox source code, and is
conjure up the right imagery" and wasn't widely known.[83] The logo was chosen
explicitly not protected as a
to make an impression while not shouting out with overdone artwork. It had to trademark
[81]

stand out in the user's mind, be easy for others to remember, and stand out without
causing too much distraction when seen among other icons.

The Firefox icon is a trademark used to designate the official Mozilla build of the Firefox software and builds of
official distribution partners.[85] For this reason, Debian and other software distributors who distribute patched or
modified versions of Firefox do not use the icon. The crash reporting service was initially closed source, but
switched with version 3 from a program called Talkback to the open source BreakPad & Socorro [86]. Other logos
are also used for specific versions of the software or its derivatives:

The current Aurora logo The current "nightly" logo Minefield logo (former name for
(alpha/pre-beta) (experimental/pre-alpha) "nightly" Firefox)

Promotion
The rapid adoption of Firefox, 100 million downloads in its first year of availability,[87] followed a series of
aggressive marketing campaigns starting in 2004 with a series of events Blake Ross and Asa Dotzler called
"marketing weeks".[88]
On September 12, 2004,[89] a marketing portal dubbed "Spread Firefox" (SFX) debuted along with the Firefox
Preview Release, creating a centralized space for the discussion of various marketing techniques. A two-page ad in
the December 16 edition of the New York Times, placed by Mozilla Foundation in coordination with Spread Firefox,
featured the names of the thousands of people worldwide who contributed to the Mozilla Foundation's fundraising
campaign to support the launch of the Firefox 1.0 web browser.[90] SFX portal enhanced the "Get Firefox" button

Firefox 6

program, giving users "referrer points" as an incentive. The site lists the top 250 referrers. From time to time, the
SFX team or SFX members launch marketing events organized at the Spread Firefox website. As a part of the
Spread Firefox campaign, there was an attempt to break the world download record with the release of Firefox 3.[91]
The "World Firefox Day" campaign started on July 15, 2006,[92] the third anniversary of the founding of the Mozilla
Foundation,[93] and ran until September 15, 2006.[94] Participants registered themselves and a friend on the website
for nomination to have their names displayed on the Firefox Friends Wall, a digital wall that will be displayed at the
headquarters of the Mozilla Foundation.
In December 2007, Mozilla launched Live Chat [95], a service allowing users to seek technical support from
volunteers. Because Live chat is kept running by volunteers, it is only available when they are online.[96]
On February 21, 2008 in honor of reaching 500 million downloads, the Firefox community celebrated by visiting
FreeRice to earn 500 million grains of rice.[97]
Some of Firefox's contributors made a crop circle of the Firefox logo in an oat field near Amity, Oregon, near the
intersection of Lafayette Highway and Walnut Hill Road.[98]
In February 2011, Mozilla announced that it would be retiring Spread Firefox (SFX). Three months later, in May
2011, Mozilla officially closed Spread Firefox. Mozilla wrote that "there are currently plans to create a new
iteration of this website [Spread Firefox] at a later date."[99]

Forbes.com called Firefox the best browser in a 2004 commentary
piece,[1] and PC World named Firefox "Product of the Year" in 2005
on their "100 Best Products of 2005" list.[2] After the release of Firefox
2 and Internet Explorer 7 in 2006, PC World reviewed both and
declared that Firefox was the better browser.[3] Which? Magazine
named Firefox its "Best Buy" web browser.[4] In 2008, CNET
compared Safari, Chrome, Firefox, and Internet Explorer in their
"Battle of the Browsers" in terms of performance, security, and
features, where Firefox was selected as a favorite.[5] In February 2012,
Tom's Hardware compared Safari 5.1.2, Google Chrome 17, Mozilla
Firefox 10, Opera 11.61 and Microsoft Internet Explorer 9 on both
Ubuntu 11.10 and Windows 7 OS (Internet Explorer & Safari excluded
from Ubuntu because of OS availability) in a "Web Browser Grand
Usage share of web browsers (March 2012 –
StatCounter)
Prix". They concluded, that based on performance, Chrome 17 was
selected as their favorite on the Ubuntu OS – but they also concluded
that on Windows OS, Firefox 10 was their favorite.[6]

Performance
In December 2005, Internet Week ran an article in which many readers
reported high memory usage in Firefox 1.5.[7] Mozilla developers said
that the higher memory use of Firefox 1.5 was at least partially due to
the new fast backwards-and-forwards (FastBack) feature.[8] Other
known causes of memory problems were malfunctioning extensions
such as Google Toolbar and some older versions of Adblock,[9] or
plug-ins, such as older versions of Adobe Acrobat Reader.[10] When
PC Magazine compared memory usage of Firefox 2, Opera 9, and
Usage share of web browsers according to Internet Explorer 7, they found that Firefox used approximately as
StatCounter. much memory as the other two browsers.[11]

Softpedia noted that Firefox 1.5 took longer to start up than other
[12]
browsers, which was confirmed by further speed tests.[13] IE 6 launched more swiftly than Firefox 1.5 on
Windows XP since many of its components were built into the OS and loaded during system startup. As a

Firefox 8

workaround for the issue, a preloader application was created that loaded components of Firefox on startup, similar
to Internet Explorer.[14] A Windows Vista feature called SuperFetch performs a similar task of preloading Firefox if
it is used often enough.
Tests performed by PC World and Zimbra in 2006 indicated that Firefox 2 used less memory than Internet Explorer
7.[3][15] Firefox 3 used less memory than Internet Explorer 7, Opera 9.50 Beta, Safari 3.1 Beta, and Firefox 2 in tests
performed by Mozilla, CyberNet, and The Browser World.[16][17][18] In mid 2009, Betanews benchmarked Firefox
3.5 and declared that it performed "nearly ten times better on XP than Microsoft Internet Explorer 7".[19]
In January 2010, Lifehacker compared the performance of Firefox 3.5, Firefox 3.6, Google Chrome 4 (stable and
Dev versions), Safari 4, and Opera (10.1 stable and 10.5 pre-alpha versions). Lifehacker timed how long browsers
took to start and reach a page (both right after boot-up and after running at least once already), timed how long
browsers took to load nine tabs at once, tested JavaScript speeds using Mozilla's Dromaeo online suite (which
implements Apple's SunSpider and Google's V8 tests) and measured memory usage using Windows 7's process
manager. They concluded that Firefox 3.5 and 3.6 were the fifth and sixth fastest browsers respectively on startup,
3.5 was third and 3.6 was sixth fastest to load nine tabs at once, 3.5 was sixth and 3.6 was fifth fastest on the
JavaScript tests. They also concluded that Firefox 3.6 was the most efficient with memory usage followed by Firefox
3.5.[20]
In February 2012, Tom's Hardware performance tested Chrome 17, Firefox 10, Internet Explorer 9, Opera 11.61, and
Safari 5.1.2 on Windows 7. Tom's Hardware summarized their tests into four categories: Performance, Efficiency,
Reliability, and Conformance. In the performance category they tested HTML 5, Java, Javascript, DOM, CSS 3,
Flash, Silverlight, and WebGL – they also tested start up time and page load time. The performance tests showed
that Firefox was either "acceptable" or "strong" in most categories, winning three categories (HTML5, HTML5
Hardware acceleration, and Java) only finishing "weak" in CSS performance. In the efficiency tests, Tom's Hardware
tested memory usage and management. In this category, it determined that Firefox was only "acceptable" at
performing light memory usage, while it was "strong" at performing heavy memory usage. In the reliability category,
Firefox performed a "strong" amount of proper page loads. In the final category, conformance, it was determined that
Firefox had "strong" conformance for Javascript and HTML5. In conclusion, Tom's Hardware determined that
Firefox was the best browser for Windows 7 OS, but that it only narrowly beat out Google Chrome.[21]

Market adoption
Downloads have continued at an increasing rate since Firefox 1.0 was released in November 2004, and as of July 31,
2009 Firefox has been downloaded over one billion times.[22] This number does not include downloads using
software updates or those from third-party websites.[23] They do not represent a user count, as one download may be
installed on many machines, one person may download the software multiple times, or the software may be obtained
from a third party. According to Mozilla, Firefox had more than 400 million users as of November 2010.[24]
In July 2010, all IBM employees (about 400,000) were asked to use Firefox as their default browser.[25]
Firefox was the second-most used web browser until December 2011, when Google Chrome surpassed it.[26]
As of May 2012, Firefox was the third most widely used browser, with approximately 25% of worldwide usage
share of web browsers.[14][15][16] According to StatCounter, Firefox usage peaked in November 2009 and usage
share would remain stagnant until October 2010 when it lost market share, a trend that would continue for over a
year. Its first consistent gains in usage share since September 2010 occurred in February and March 2012 before
making minor losses in April 2012.[15]

Platform support
Mozilla provides development builds of Firefox in the following channels: "Beta", "Aurora", and "Nightly". As
of July 2012, Firefox 15 beta is in the "Beta" channel, Firefox 16 alpha is in the "Aurora" channel, and Firefox 17
pre-alpha is in the "Nightly" channel.
Features planned for future versions include silent updating so that version increments will not bother the user,
although the user will be able to disable that function.[85] A different looking user-interface called "Australis" is also
planned.[86]

Firefox for mobile
Firefox for mobile, codenamed Fennec, is a web browser for smaller non-PC
devices, mobile phones and PDAs. It was first released for the Nokia Maemo
operating system (specifically the Nokia N900) on January 28, 2010.[87]
Version 4 for Android and Maemo was released on March 29, 2011.[88] The
browser's version number was bumped from version 2 to version 4 to
synchronize with all future desktop releases of Firefox since the rendering
engines used in both browsers are the same.[89] Version 7 was the last release
for Maemo on the N900.[90] The user interface is completely redesigned and
optimized for small screens, the controls are hidden away so that only the web
content is shown on screen, and it uses touchscreen interaction methods. It
includes the Awesomebar, tabbed browsing, Add-on support, password
manager, location-aware browsing, and the ability to synchronize with the
user's computer Firefox browser using Firefox Sync.[91]

Firefox ESR
Firefox for mobile 14.0 on Android
Firefox ESR is a version of Firefox for organizations and other adopters who
need extended support for mass deployments.[92] Unlike the regular ("rapid")
releases, the ESR will be updated with new features and performance enhancements annually, receiving regular
security updates during the year.[93]

64-bit support

Operating System 64-bit support

Windows No

Mac OS X Yes

Linux Yes

64-bit support for Firefox is inconsistent across operating systems. 64-bit is supported by Mozilla in Mac OS X and
Linux, but there are no official 64-bit releases for Windows OS. Mozilla does provide a 64-bit version for their
Firefox nightly builds, but they are considered unstable by Mozilla.[94][95]
The official releases of Firefox for Mac OS X are universal builds that include both 32-bit and 64-bit versions of the
browser in one package, and have been this way since Firefox 4. A typical browsing session uses a combination of
the 64-bit browser process and a 32-bit plugin process, because some popular plugins still are 32-bit.[96]

Firefox 19

Mozilla made Firefox for Linux 64-bit a priority with the release of Firefox 4, labeling it as tier 1 priority.[97][98]
Since being labeled tier 1, Mozilla has been providing official 64-bit releases for its browser for the Linux
OS.[99][100] Vendor-backed 64-bit support has existed for Linux based OS's such as Novell-Suse Linux, Red Hat
Enterprise Linux, and Ubuntu prior to Mozilla's support of 64-bit, even though vendors were faced with the
challenge of having to turn off the 64-bit JIT compiler due to its instability prior to Firefox 4.[101][102][103]

System requirements
Browsers compiled from Firefox source code may run on various operating systems; however, officially distributed
binaries are meant for the following: Microsoft Windows (XP SP2/SP3, Server 2003, Vista or 7), Mac OS X 10.5,
Mac OS X 10.6 and Linux (with the following libraries installed: GTK+ 2.10 or higher, GLib 2.12 or higher, Pango
1.14 or higher, X.Org 1.0 or higher (1.7 or higher is recommended), libstdc++ 4.3 or higher).[104]

Firefox 20

Affiliations

Google
The Mozilla Corporation's relationship with Google has been noted in the popular press,[114][115] especially with
regard to their paid referral agreement. The release of the anti-phishing protection in Firefox 2 in particular raised
considerable controversy:[116] anti-phishing protection enabled by default is based on a list updated by twice-hourly
downloads to the user's computer from Google's server.[117] The user cannot change the data provider within the
GUI,[118] and is not informed who the default data provider is. The browser also sends Google's cookie with each
update request.[119] Some internet privacy advocacy groups have expressed concerns surrounding Google's possible
uses of this data, especially that Firefox's privacy policy states that Google may share information (that is not
personally identifying) gathered with "safebrowsing" service with third parties, including business partners.[120]
Following Google CEO Eric Schmidt's comments in December 2009 regarding privacy during a CNBC show,[121]
Asa Dotzler, Mozilla's director of community development suggested that users use the Bing search engine instead
of Google search.[122] Google also promoted Firefox through YouTube until the release of Google Chrome. In
August 2009, Mozilla Security assisted Google by pointing out a security flaw in Google's Chrome browser.[123]
In 2005, the Mozilla Foundation and Mozilla Corporation had a combined revenue of US$52.9 million, with
approximately 95% derived from search engine royalties.[124][125] In 2006, the Mozilla Foundation and Mozilla
Corporation had a combined revenue of US$66.9 million, with approximately 90% derived from search engine
royalties.[124][126] In 2007, the Mozilla Foundation and Mozilla Corporation had a combined revenue of US$81
million, with 88% of this sum (US$66 million) from Google.[127][128] In 2008, both Mozilla organizations had a
combined revenue of US$78.6 million, with 91% coming from Google.[129] The Mozilla Foundation and
Corporation are being audited by the IRS with the possibility of having its non-profit status called into
question.[127][129][130]

Microsoft
Microsoft's head of Australian operations, Steve Vamos, stated in late 2004 that he did not see Firefox as a threat and
that there was not significant demand for the feature-set of Firefox among Microsoft's users.[131] Microsoft Chairman
Bill Gates has used Firefox, but has commented that "it's just another browser, and IE [Microsoft's Internet Explorer]
is better".[132]
A Microsoft SEC filing on June 30, 2005 acknowledged that "competitors such as Mozilla offer software that
competes with the Internet Explorer Web browsing capabilities of our Windows operating system products."[133] The
release of Internet Explorer 7 was fast tracked, and included functionality that was previously available in Firefox
and other browsers, such as tabbed browsing and RSS feeds.[134]
Despite the cold reception from Microsoft's top management, the Internet Explorer development team maintains a
relationship with Mozilla. They meet regularly to discuss web standards such as extended validation certificates.[135]
In 2005, Mozilla agreed to allow Microsoft to use its Web feed logo in the interest of common graphical
representation of the Web feeds feature.[136]
In August 2006, Microsoft offered to help Mozilla integrate Firefox with the then-forthcoming Windows Vista,[137]
an offer Mozilla accepted.[138]
In October 2006, as congratulations for a successful ship of Firefox 2, the Internet Explorer 7 development team sent
a cake to Mozilla.[139][140] As a nod to the browser wars, some jokingly suggested that Mozilla send a cake back
along with the recipe, in reference to the open-source software movement.[141] The IE development team sent
another cake on June 17, 2008, upon the successful release of Firefox 3,[142] again on March 22, 2011, for Firefox
4,[143] and yet again for the Firefox 5 release.[144]

Firefox 21

In November 2007, Jeff Jones (a "security strategy director" in Microsoft's Trustworthy Computing Group) criticized
Firefox, claiming that Internet Explorer experienced fewer vulnerabilities and fewer higher severity vulnerabilities
than Firefox in typical enterprise scenarios.[145] Mozilla developer Mike Shaver discounted the study, citing
Microsoft's bundling of security fixes and the study's focus on fixes, rather than vulnerabilities, as crucial flaws.[146]
In February 2009, Microsoft released Service Pack 1 for version 3.5 of the .NET Framework. This update also
installed Microsoft .NET Framework Assistant add-on (enabling ClickOnce support).[147] The update received media
attention after users discovered that the add-on could not be uninstalled through the add-ons interface.[148][149]
Several hours after the website Annoyances.org posted an article regarding this update, Microsoft employee Brad
Abrams posted in his blog Microsoft's explanation for why the add-on was installed, and also included detailed
instructions on how to remove it.[150] However, the only way to get rid of this extension was to modify manually the
Windows Registry, which could cause Windows systems to fail to boot up if not done correctly.[148]
On October 16, 2009, Mozilla blocked all versions of Microsoft .NET Framework Assistant from being used with
Firefox and from the Mozilla Add-ons service.[151] Two days later, the add-on was removed from the blocklist after
confirmation from Microsoft that it is not a vector for vulnerabilities.[152][153] Version 1.1 (released on June 10, 2009
to the Mozilla Add-ons service) and later of the Microsoft .NET Framework Assistant allows the user to disable and
uninstall in the normal fashion.[154]
Firefox was one of the twelve browsers offered to European Economic Area users of Microsoft Windows in 2010 –
see BrowserChoice.eu.[155]

History of Firefox
The Mozilla Firefox project was created by Dave Hyatt and Blake Ross as an experimental branch of the Mozilla
browser. Firefox 1.0 was released on November 9, 2004. Firefox 1.5 was released on November 29, 2005. Version
2.0 was released on October 24, 2006. Firefox 3.0 was released on June 17, 2008, with Version 3.5 and Version 3.6
released on June 30, 2009 and January 21, 2010 respectively. Version 4.0 was released on March 22, 2011. With
Version 5.0 onwards the rapid release cycle was realised which envisions a new major version release every six
weeks on Tuesday. The latest version, Firefox 14.0.1 was released on July 17, 2012.

History

Naming
The project which became Firefox started as an experimental branch of the Mozilla Suite called m/b (or
mozilla/browser). After it had been sufficiently developed, binaries for public testing appeared in September 2002
under the name Phoenix.
The Phoenix name was kept until April 14, 2003, when it was changed because of a trademark dispute with the BIOS
manufacturer, Phoenix Technologies (which produces a BIOS-based browser called Phoenix FirstWare Connect).
The new name, Firebird, met with mixed reactions, particularly as the Firebird database server already carried the
name. In response, the Mozilla Foundation stated that the browser should always bear the name Mozilla Firebird to
avoid confusion with the database software. Continuing pressure from the Firebird community forced another
change,[1] and on February 9, 2004 the project was renamed Mozilla Firefox (or Firefox for short).[2]
The name "Firefox" (a reference to the red panda)[3] was chosen for its similarity to "Firebird", but also for its
uniqueness in the computing industry. To ensure that no further name changes would be necessary, the Mozilla
Foundation began the process of registering Firefox[4] as a trademark with the United States Patent and Trademark
Office in December 2003. This trademark process led to a delay of several months in the release of Firefox 0.8 when


the foundation discovered that Firefox had already been registered as a trademark in the UK[5] for Charlton
Company software.[6] The situation was resolved when the foundation was given a license to use Charlton's
European trademark.

Early versions
Hyatt, Ross, Hewitt and Chanial's[7] browser was created to
combat the software bloat of the Mozilla Suite (codenamed,
internally referred to, and continued by the community as
SeaMonkey), which integrated features such as IRC, mail and
news, and WYSIWYG HTML editing into one software suite.
Firefox retains the cross-platform nature of the original Mozilla
browser, using the XUL user interface markup language. The use
of XUL makes it possible to extend the browser's capabilities
through the use of extensions and themes. The development and
installation processes of these add-ons raised security concerns,
Phoenix 0.1, the first official release
and with the release of Firefox 0.9, the Mozilla Foundation opened
a Mozilla Update website containing "approved" themes and
extensions. The use of XUL sets Firefox apart from other browsers, including other projects based on Mozilla's
Gecko layout engine and most other browsers, which use interfaces native to their respective platforms (Galeon and
Epiphany use GTK+; K-Meleon uses MFC; and Camino uses Cocoa). Many of these projects were started before
Firefox, and probably served as inspiration.

On February 5, 2004, business and IT consulting company AMS categorized Mozilla Firefox (then known as
Firebird) as a "Tier 1" ("Best of Breed") open source product, considering it technically strong and virtually
risk-free.[8]

Version 1.0
Firefox 1.0 was released on November 9, 2004[9]. The launch of
version 1.0 was accompanied by "a respectable amount of
pre-launch fervor"[10] including a fan-organized campaign to run a
full-page ad in The New York Times.
Although the Mozilla Foundation had intended to make the
Mozilla Suite obsolete and replace it with Firefox, the Foundation
continued to maintain the suite until April 12, 2006[11] because it
had many corporate users and was bundled with other software.
The Mozilla community (as opposed to the Foundation) continues
to release new versions of the suite, using the product name Firefox 1.0, the first release targeted for general public

SeaMonkey to avoid confusion with the original Mozilla Suite.


Version 1.5
On June 23, 2005, the Mozilla Foundation announced that Firefox 1.1 (which
became Firefox 1.5) and other new Mozilla products would no longer support
Mac OS X v10.1, in order to improve the quality of Firefox releases on Mac
OS X v10.2 and above. Mac 10.1 users could still use Firefox versions from
the 1.0.x branch (e.g. Firefox 1.0.7).

"Deer Park", the codename of the Firefox
1.1 and 1.5 Alphas, did not include
Firefox branding.

Firefox 1.5 was released on November 30, 2005. While Firefox 1.5 was
originally slated to arrive later, the Mozilla Foundation abandoned the 1.1
release plan after the first two 1.1 alpha builds, merging it with the feature set
of 1.5, which ended up being released later than the original 1.1 date. The
new version resynchronized the code base of the release builds (as opposed to
nightly builds) with the core "trunk", which contained additional features not
available in 1.0, as it branched from the trunk around the 0.9 release. As such,
there was a backlog of bug fixes between 0.9 and the release of 1.0, which
were made available in 1.5. Version 1.5 implemented a new Mac-like options
Updated options window introduced in
interface [12], the subject of much criticism from Windows and Linux users,
Firefox 1.5
with a "Sanitize [13]" action to allow someone to clear their privacy-related
information without manually clicking the "Clear All" button. In Firefox 1.5,
a user could clear all privacy-related settings simply by exiting the browser or using a keyboard shortcut, depending
on their settings. Moreover, the software update system was improved [14] (with binary patches now possible). There
were also improvements [15] in the extension management system, with a number of new developer features [16].

In addition, Firefox 1.5 had preliminary SVG 1.1 support.[17]
Alpha builds of Firefox 1.5 (1.1a1 and 1.1a2) did not carry Firefox branding; they were labeled "Deer Park" (which
was Firefox 1.5's internal codename) and contained a different program icon. This was done to dissuade end-users
from downloading preview versions, which are intended for developers only.
Firefox 1.5.0.12 was the final version supported on Windows 95.


Version 2
On October 24, 2006, Mozilla released Firefox 2. This
version includes updates to the tabbed browsing
environment; the extensions manager; the GUI
(Graphical User Interface); and the find, search and
software update engines; a new session restore feature;
inline spell checking; and an anti-phishing feature
which was implemented by Google as an
extension,[18][19] and later merged into the program
itself.[20] In December 2007, Firefox Live Chat was
launched. It allows users to ask volunteers questions
through a system powered by Jive Software, with
guaranteed hours of operation and the possibility of Mozilla Firefox 2.0.0.12 running on Ubuntu
[21]
help after hours. Firefox 2.0.0.20 is the final version
which can run under an unmodified installation of Windows NT 4.0, Windows 98, and Windows ME.[22]

Mozilla Firefox 2.0.0.x was the final version supported on Windows NT 4.0, 98 and Me. Mozilla Corporation
announced it would not develop new versions of Firefox 2 after the 2.0.0.20 release, but continued Firefox 2
development as long as other programs, such as Thunderbird mail client, depended on it. The final internal release
was 2.0.0.22, released in late April 2009.

Version 3
Firefox 3 was released on June 17, 2008,[23] by the
Mozilla Corporation. Firefox 3 uses version 1.9 of the
Mozilla Gecko layout engine for displaying web pages.
This version fixes many bugs, improves standard
compliance, and implements new web APIs.[24] Other
new features include a redesigned download manager, a
new "Places" system for storing bookmarks and
history, and separate themes for different operating
systems. Tabbed browsing was more popularised in this
version. The final version under 3.0 is Firefox 3.0.19.

Development stretches back to the first Firefox 3 beta
(under the codename 'Gran Paradiso'[25]) which had Mozilla Firefox 3.0 on Ubuntu
been released several months earlier on 19 November
2007,[26] and was followed by several more beta releases in spring 2008 culminating in the June release.[27] Firefox
3 had more than 8 million unique downloads the day it was released, setting a Guinness World Record.[28]


Version 3.5
Version 3.5, codenamed Shiretoko,[29] adds
a variety of new features to Firefox. Initially
numbered Firefox 3.1, Mozilla developers
decided to change the numbering of the
release to 3.5, in order to reflect a
significantly greater scope of changes than
originally planned.[30] The final release was
on June 30, 2009. The changes included
much faster performance thanks to an
upgrade to SpiderMonkey JavaScript engine
called TraceMonkey and rendering
[31]
improvements, and support for the
<video> and <audio> tags as defined in
the HTML 5 specification, with a goal to
offer video playback without being
encumbered by patent problems associated Firefox 3.5 on Ubuntu
[32]
with many video technologies. Cross-site
XMLHttpRequests (XHR), which can allow for more powerful web applications and an easier way to implement
mashups, are also implemented in 3.5.[33] A new global JSON object contains native functions to efficiently and
safely serialize and deserialize JSON objects, as specified by the ECMAScript 3.1 draft.[34] Full CSS 3 selector [35]
support has been added. Firefox 3.5 uses the Gecko 1.9.1 engine, which includes a few features that were not
included in the 3.0 release. Multi-touch trackpad support was also added to the release, including gesture support like
pinching for zooming and swiping for back and forward.[36] Firefox 3.5 also features an updated logo.[37]

Version 3.6
Version 3.6, released on January 21, 2010, uses the Gecko 1.9.2 engine and includes several interface improvements,
such as "personas". This release was referred to as 3.2 before 3.1 was changed to 3.5. The codename for this version
was Namoroka.
One minor update to Firefox 3.6, version 3.6.4 (code-named Lorentz) is the first minor update to make non-intrusive
changes other than minor stability and security fixes.[38] It adds Out of Process Plugins (OOPP), which runs plugins
in a separate process, allowing Firefox to recover from plugin crashes.
Firefox 3.6.6 lengthens the amount of time a plug-in is allowed to be unresponsive before the plug-in quits.[39]
Support for Firefox 3.6 ended on 24 April 2012.[40]


Version 4.0
Firefox 3.7 (Gecko 1.9.3) Alpha 1 was
released on February 10, 2010.[41][42] Alpha
2 was released on March 1, 2010, Alpha 3
on March 17, Alpha 4 on April 12, and
Alpha 5 on June 16. The version number
was changed to 4.0 (and Gecko's was
changed to 2.0) starting with Beta 1,
released on July 6, 2010. Beta 2 was
released on July 27, Beta 3 on August 11,
Beta 4 on August 24, Beta 5 on September
7, Beta 6 (a chemspill release) on September
14. After major delays, Beta 7 was finally

released on November 10. Beta 7 was
followed by Beta 8, released on December
21. Beta 9 was released on January 14, 2011, Beta 10 on January 25, Beta 11 on February 8, and Beta 12 on
February 12. Firefox then moved into the RC stage.[43] The Final Version of Firefox 4 was released on March 22,
2011.[44]

Version 4 brought a new user interface and is said to be faster.[45] Early mockups of the new interface on Windows,
Mac OS X, and Linux were first made available in July 2009.[46][47][48] Other new features included improved
notifications, tab groups, application tabs, a redesigned add-on manager, integration with Firefox Sync, and support
for multitouch displays.[49][50][51][52][53]
On October 13, 2006, Brendan Eich, Mozilla's Chief Technology Officer, wrote about the plans for "Mozilla 2",
referring to the most comprehensive iteration (since its creation) of the overall platform on which Firefox and other
Mozilla products run.[54] Most of the objectives were gradually incorporated into Firefox through versions 3.0, 3.5,
and 3.6. The largest changes, however, were planned for Firefox 4.
Firefox 4 was based on the Gecko 2.0 engine, which added or improved support for HTML5, CSS3, WebM, and
WebGL.[55][56] It also included a new JavaScript engine (JägerMonkey) and better XPCOM APIs.[57]

Rapid release
In April 2011, the development process was split into several "channels", each working on a build in a different stage
of development. The most recent available build is called "Nightly Builds" and offers the latest, untested features and
updates. The "Aurora" build is up to six weeks behind "Nightly" and offers functionality that has undergone basic
testing. The "Beta" channel is another six weeks away. It provides improved stability over the nightly builds and is
the first development milestone that has the "Firefox" logo. "Release" is the current official version of Firefox. New
releases are planned to occur at six week intervals.[58] The stated aim of this faster-paced process is to get new
features to users faster.[59] This accelerated release cycle was met with criticism by users, as it often broke addon
compatibility,[60] as well as those who believe Firefox was simply trying to increase its version number to compare
with other browsers such as Google Chrome.[61]


Version 5
Firefox 5 was released on June 21, 2011,[62] three months after the major release of Firefox 4. Firefox 5 is the first
release in Mozilla's new rapid release plan, matching Google Chrome's rapid release schedule and rapid version
number increments.[63] Version 5 improved the speed of the browser significantly when it was asked to perform web
related tasks, such as loading pages with lots of combo-boxes and loading pages utilizing MathML. Mozilla also
integrated the HTML5 video WebM standard into the browser, allowing playback of WebM video.[64]

Version 6

Mozilla released its Mozilla Firefox 6.0 on August 16, 2011. The
update brought: permissions manager, new address bar highlighting
(the domain name is black while the rest of the URL is gray[65]),
streamlining the look of the site identity block, quicker startup time, a
ScratchPad JavaScript compiler, and many other new features.[66]

Version 7

Firefox 7, released September 27, 2011, uses as much as 50% less
memory than Firefox 4 as a result of the MemShrink project to reduce
ScratchPad
Firefox memory usage.[67][68][69] Mozilla Firefox 7.0.1 was released a
few days later, fixing a rare but serious issue with add-ons not being
detected by the browser.[70] The "http://" protocol indicator no longer appears in the URL.[65]

Version 8
Firefox 8 was released on November 8, 2011. Firefox 8 verified that users really wanted any previously installed
add-ons. Upon installation, a dialog box prompted users to enable or disable the add-ons. Add-ons installed by
third-party programs were disabled by default, but user-installed add-ons were enabled by default. Mozilla judged
that third-party-installed add-ons were problematic, taking away user control, lagging behind on compatibility and
security updates, slowing down Firefox start-up and page loading time, and cluttering the interface with unused
toolbars.[71]

Version 9
Firefox 9 was released on December 20, 2011; version 9.0.1 was released a day later. Firefox 9 includes various new
features such as Type Inference, which boosts JavaScript performance by up to 30%, improved theme integration for
Mac OS X Lion, added two finger swipe navigation for Mac OS X Lion, added support for querying Do Not Track
status via JavaScript, added support for font-stretch, improved support for text-overflow, improved standards support
for HTML5, MathML, and CSS, and fixed several security problems. It also features a large list of bug fixes.[72]

Version 10

Firefox 10 was released on January 31, 2012. It is the first official
extended support release. Firefox 10 hides the forward arrow button
until there is a website to go forward to, or it is manually activated.[73]
Firefox 10 adds a Full Screen API and improved WebGL
performance.[74]
Firefox 10 assumed all add-ons are compatible with version 10, as long
as they are written for at least Firefox 4. The add-on developer is able Style Inspector
to alert Mozilla that the add-on is incompatible, overriding
compatibility with version 10 or later. This new rule also does not apply to themes.[75]


Firefox 10 added the CSS Style Inspector to the Page Inspector, which allow users to check out a site's structure and
edit the CSS without leaving the browser.[76]
Firefox 10 added support for CSS 3D Transforms and for anti-aliasing in the WebGL standard for
hardware-accelerated 3D graphics. These updates mean that complex site and Web app animations will render more
smoothly in Firefox, and that developers can animate 2D objects into 3D without plug-ins.[74]

Version 11

Firefox 11 was released on March 13, 2012. Firefox 11 introduced
many new features, including Google Chrome migration, SPDY
integrated services, Page Inspector Tilt (3D View), Add-on Sync,
redesigned HTML5 video controls, and the Style Editor (CSS).[77] The
update also fixed many bugs, and improved developer tools.[78]

Version 12
3D Page Inspector
Firefox 12 was released on April 24, 2012. Firefox 12 introduced few
new features, but it made many changes and laid the ground work for
future releases. Firefox 12 removed the UAC prompt in Windows,
added line numbers in the "Page Source" and centered find in page
results. There were 89 improvements to Web Console, Scratchpad,
Style Editor, Page Inspector, Style Inspector, HTML view and Page
Inspector 3D view (Tilt).[79] Many bugs were fixed, as well as many
other minor under-the-hood changes.[80][81] Firefox 12 is the final
release to support Windows 2000 and Windows XP RTM &
SP1.[82][83]

Firefox for Ubuntu

Version 13

Firefox 13 was released on June 5th, 2012.[58] Firefox 13 adds and
updates several features, such as an updated new tab[84] and home tab
page.[85] The updated new tab page is a feature similar to the Speed
Dial already present in Opera, Google Chrome, Apple Safari, and
Windows Internet Explorer. The new tab page will display nine of the
user's most visited websites, along with a cached image.

In addition to the updated new tab and home tab page, Mozilla has
added a user profile cleaner/reset, reduced hang times, and
implemented tabs on demand.[86] The user profile cleaner/reset New Tab page
provides a way for users to fix Firefox errors and glitches that may
occur.[87] Mozilla's tabs on demand restores tabs that were open in the previous session, but will keep the tabs
unloaded until the user requests to view the page.[88]

Starting with this version, Windows support was exclusively for Windows XP SP2/SP3, Windows Vista, &
Windows 7.


Version 14

Firefox 14.0 for Android was released on June 26, 2012, just outside
the regular release schedule of the web browser.[89][58] In order to sync
up the version numbers of the desktop and mobile version of Firefox,
Mozilla decided to release Firefox 14.0.1 for mobile and desktop on
July 17, 2012, instead of Firefox 14.0 for the desktop and Firefox
14.0.1 for mobile clients.[89] Mozilla plans to implement support for
Windows 8 in Firefox 14. Firefox for Metro, like all other Metro apps,
will be fullscreen, focused on touch interactions, and connected to the Home tab page
rest of the Metro environment. Firefox will support three "snap" states
— fullscreen, ~1/6th screen and ~5/6th screen. The "snap" state Firefox uses depends on how the user "docks" the
other application.[90]

A new hang detector (similar to how Mozilla currently collects other data) allows Mozilla to collect, analyze, and
identify the cause of the browser freezing/hanging. Mozilla will use this information to improve the responsiveness
of Firefox for future releases.[91]
In addition to tackling freezing and not-responding errors that occur because of Firefox, Mozilla implemented opt-in
activation for plugins such as Flash and Java. Mozilla wants to reduce potential problems that could arise through the
unwanted use of third-party applications (malware, freezing, etc.).[92]
URL complete will suggest the website that Firefox believes the user plans on visiting. It does this by inserting the
remaining characters into the URL form box.[93]
Firefox 14 has an optional GStreamer back-end for HTML5 video tag playback. This allows playback of H.264 if the
codec is installed as a GStreamer plugin. GStreamer support is not enabled in the official builds, but can be enabled
at compile time.
The first beta version of Firefox 14 was not beta 1, but beta 6[94] and was released on June 5th, 2012.

Future releases
Test builds can be downloaded from the Firefox development channels: "Beta", "Aurora", and "Nightly".
As of July 2012, Firefox 15 beta is in the "Beta" channel, Firefox 16 alpha is in the "Aurora" channel, and Firefox 17
pre-alpha is in the "Nightly" channel.
Features planned for future versions include silent updating so that version increments will not bother the user,
although the user will be able to disable that function.[95] A different looking user-interface called "Australis" is also
planned.[96]

Version 15
Firefox 15 is scheduled for August 28, 2012 release.[58] Mozilla has provided this list of features that it hopes to
implement, but these features are likely to be pushed back to a later release version.[97]
This version includes a "Responsive Design View" developer tool[98], adds support for the Opus audio format [99]
and adds preliminary native PDF support.
Silent updates will automatically update Firefox to the latest version without notifying the user,[100] a feature that the
web browsers Google Chrome and Internet Explorer 8 and above have already implemented.[101][102]
Mozilla will improve regular start-up time for Windows users.[103]


Version 16
Firefox 16 is scheduled to be released on October 9, 2012.
Current plans for Firefox 16 call for fixing of bugs still outstanding involving support of new features in Lion,
improvements to start-up speed when a user wants to restore a previous session.[104], and support for viewing PDF
files inline without a plugin. The panel-based download manager originally scheduled for Firefox 15 was retargeted
to Firefox 16 due to too many bugs.[105]

Version 17
Firefox 17 is scheduled to be released on November 20, 2012.
Firefox 17 ESR is also scheduled to be released on November 20, 2012.
Very few features are targeted for Firefox 17 at this time - there are only two: Improved display of location bar
results[106] and improvements to the silent update mechanism for users with incompatible add-ons[107].

Extended Support Release
In January 2012, the Mozilla Foundation announced the availability of an Extended Support Release version of
Firefox.[108] Firefox ESR is intended for groups who deploy and maintain the desktop environment in large
organizations such as universities and other schools, county or city governments and businesses.
ESR include silent, automatic updating, continuity of support through 9 cycles (54 weeks), with the final 2 cycles
overlapping the next version.
Example: ESR jumps from 10.0 to 17.0, then to 24.0 etc.
Every six weeks when a new mainstream Firefox release is made under the rapid release cycle, a regular security
update would also be released for the then-current ESR version. For example, ESR 10.0.1 would be expected to be
released at the same time as Firefox 11. Then ESR 10.0.2, 10.0.3 etc. would also be released. At Firefox 16, ESR
would reach version 10.0.6. At Firefox 17 and Firefox 18, there would be two ESR versions supported. Respectively,
ESR 10.0.7 and ESR 17.0.0; ESR 10.0.8, ESR 17.0.1. Finally, when Firefox reaches 19.0, ESR 10.0 would go
end-of-life alongside the release of ESR 17.0.2. The cycle repeats again.
Note: Users can only manually get ESR 17.0.x from ESR 10.0.x through Firefox Updater.[109][110]
However, severe flaws discovered in a shipping version of Firefox may disrupt the regular release schedule. For
example, two unplanned releases of Firefox 10.0.1 and 10.0.2 were made within 17 days of the initial release of
Firefox 10. Firefox ESR 10.0.1 and 10.0.2 were also released at the same times to address the same flaws. Therefore,
assuming no further critical flaws are discovered in the interim, the next regular scheduled security and stability
update for Firefox ESR 10.0.x, coinciding with Firefox 11, will actually be Firefox ESR 10.0.3, and all future
versions of Firefox ESR 10.0.x will be similarly offset relative to the version progression presented above.


"Delicious delicacies"
Early Firefox releases featured a preferences panel that described cookies
thus: "Cookies are delicious delicacies".
The phrase was representative of the programmers' quirky sense of humor and
was a reflection of the free software movement's unconventional approach.
The phrase became something of a cult legend and was even featured in an
O'Reilly computer book.
The original text was inserted by Blake Ross, one of the lead developers of
Firefox, because, he said [111], "describing something so complicated in such
A screenshot showing the "cookies are
a small space was quite frankly the last thing I wanted to worry about after delicious delicacies" line
rewriting the cookie manager".

However, in reflection of the growing acceptance and use of the Firefox browser in the Internet mainstream, the text
was later changed. It was labeled a bug,[112] and was "fixed" by Mike Connor to read, "Cookies are pieces of
information stored by web pages on your computer. They are used to remember login information and other data."
The revision was regarded as more likely to be helpful to less technically oriented computer users who were now
using Firefox—representing Mozilla's desire to appeal to mainstream users.
The text became a popular in-joke and on August 2004, the Delicious Delicacies extension [113], no longer
maintained or updated, was released by Jesse Ruderman. The extension restored the old description of cookies,
available in several languages.
As of Firefox 2.0, cookies are no longer described in the preferences window.

Mozilla
Mozilla is a brand name originally coined by Netscape Communications Corporation for use in reference to the
company's application software, and later used to refer to various open source software initiatives originating at
Netscape.
Mozilla was originally the codename for the defunct Netscape Navigator software project, along with Netscape's
mascot, a cartoon reptile inspired by Godzilla.
When Netscape Navigator was released as open source software, Mozilla was the name of the development project
and community, along with the project's first product, the Mozilla Application Suite (later renamed SeaMonkey).
Following the closure of the Netscape project, the name was adopted by the Mozilla Foundation and its subsidiary
the Mozilla Corporation, who continue to promote the original project's goals in association with the wider Mozilla
community.

Codename of Netscape Navigator
Historically, Mozilla had been used internally as a codename for the Netscape Navigator web browser from its
beginning. Jamie Zawinski came up with the name during a meeting while working at the company.[1] The name was
created as a portmanteau of the words "Mosaic killer",[2] hinting that Netscape would be the end to the (then only)
competitor browser, Mosaic. The logo was a reference to the name of the fictional monster Godzilla.

Mascot of Netscape
Mozilla was the mascot of the now-disbanded Netscape Communications Corporation, formerly called Mosaic
Communications Corporation. Initially, the mascot took various forms, including that of a helmeted astronaut or
"spaceman", but the eventual choice was a Godzilla-like lizard thought to go well with the name. It was designed by
Dave Titus in 1994.
Mozilla was featured prominently on Netscape's website in the company's early years. However, the need to project a
more "professional" image (especially towards corporate clients) led to it being removed. Mozilla continued to be
used inside Netscape, though, often featured on T-shirts given to staff or on artwork adorning the walls of the
Netscape campus in Mountain View. The color of the Mozilla lizard changed from its original green to a red version
of the monster after the source code of the Netscape browser was released.[3]
When Netscape acquired the website directory NewHoo in 1998, they re-branded it the Open Directory Project with
the nickname "dmoz" (Directory of Mozilla) due to its similarity to the Mozilla project. An image of Mozilla was
placed on every page of the site, which remains the case today. Netscape Communications continued using the image
of the red Mozilla in its iconography [4] in the Mozilla.org project web site.

Mozilla 43

Mozilla Project
"Mozilla" is the every-day name for the free and open-source software project that was founded in 1998 in order to
create a next-generation Internet suite for Netscape. On 15 July 2003, the organization was formally registered as a
non-profit organization, and became the Mozilla Foundation. The foundation now creates and maintains the Mozilla
Firefox browser and Mozilla Thunderbird email application, among other software, and holds the Mozilla
trademarks.

Mozilla Corporation
On 3 August 2005, the Mozilla Foundation announced the creation of Mozilla Corporation, described as "a taxable
subsidiary that serves the non-profit, public benefit goals of its parent, the Mozilla Foundation, and that will be
responsible for product development, marketing and distribution of Mozilla products."[5]

Mozilla Application Suite
The Mozilla project's initial software offering was known as the
"Mozilla Application Suite". Its origin came from Netscape.
January 22, 1998 Netscape announced that it would be relicensing
its source code for future development.[6] In March 1998,
Netscape released most of the code for its popular Netscape
Communicator Internet suite under a free software/open source
license, the Netscape Public License. The application developed
from this was named Mozilla, which also was the codename of the
original Netscape Navigator. After a series of pre-releases, Mozilla
Startup screen of the Mozilla Application Suite for
1.0 was released on June 5, 2002.
Mac OS 9 featuring the Mozilla mascot

In 2004, the Mozilla Foundation announced that it would be no
longer maintaining the suite, in order to focus its attention on the standalone products Firefox and Thunderbird,
which are built on the same Gecko layout engine. The suite was renamed SeaMonkey and was handed over to the
SeaMonkey Council, which has continued the development within the Mozilla community.

Application Framework
The term Mozilla is also occasionally used to refer to the Mozilla application framework, a cross-platform
application framework for writing applications that can run on multiple operating systems. It consists most notably
of the Gecko layout engine, but also the XUL user-interface toolkit, the Necko networking library, and other
components. This is the core that all Mozilla-based browsers and applications are built from.

Codebase
Source code for Mozilla software projects such as Firefox, Thunderbird, and XULRunner are managed collectively
in a single Mercurial repository. This large codebase is referred to as the Mozilla codebase, the Mozilla source code,
or just Mozilla.
The Mozilla codebase was originally released under the Netscape Public License. Shortly afterwards, the license was
updated to version 1.1 and renamed the Mozilla Public License (MPL). The Free Software Foundation and others
noted that a GPL-licensed module and an MPL-license module cannot be legally linked, and they recommend that
developers not use the MPL for this reason.[7] To address this concern, between 2001 and 2004 the Mozilla
Foundation relicensed all of the Mozilla codebase under the GNU General Public License and GNU Lesser General
Public License as well as the Mozilla Public License.[8]

Mozilla 44

Community
Mozilla also refers to a loosely-knit community of people, known as "Mozillians",[9] dedicated to using, developing,
spreading and supporting Mozilla-related products and advancing the goals of the Open Web according to the
Mozilla Manifesto.[10] Its activities include:
• Localization - translating Mozilla software and websites to other languages.
• Evangelizing for web standards in blogs and at relevant events. This is sometimes done independently and
sometimes in a more structured way with programs such as "Mozilla Reps".[11][12]
• Organizing local and international meetings of Mozilla activists, such as Mozilla Camp, Mozilla Summit and
Drumbeat.
• Providing support to users of Mozilla products through online forums, and IRC.
• Organizing educational events for school children, teaching them how to understand the World Wide Web and
develop web content, with programs such as "Hackasaurus".[13]
• Testing future ("beta") release of Mozilla products and reporting bugs.
Many of these activities are done on a voluntary basis, and some are sponsored by the Mozilla Foundation.

User Agent String
When users visit a website (using "user agent" software such as a web browser), a text string is generally sent to
identify the user agent to the web server. It is known as the "user agent string". The Netscape web browser identified
itself as "Mozilla/<version>" followed by some information about the operating system it was running on.
Because the Netscape browser initially implemented many features not available in other browsers and quickly came
to dominate the market, a number of web sites were designed to work, or work fully, only when they detected an
appropriate version of Mozilla in the user agent string. Thus, competing browsers began to emulate ("cloak" or
"spoof") this string in order to also work with those sites. The earliest example of this is Internet Explorer's use of a
user agent string beginning "Mozilla/<version> (compatible; MSIE <version>...", in order to
receive content intended for Netscape, its main rival at the time of its development. This format of user agent string
has since been copied by other user agents, and persisted even after Internet Explorer came to dominate the browser
market.

The Mozilla Foundation is a non-profit organization that exists to support and lead the open source Mozilla project.
The organization sets the policies that govern development, operates key infrastructure and controls trademarks and
other intellectual property. It owns a taxable subsidiary: the Mozilla Corporation, which employs many Mozilla
developers and coordinates releases of the Mozilla Firefox web browser and Mozilla Thunderbird email client. The
subsidiary is 100% owned by the parent, and therefore follows the same non-profit principles. The Mozilla
Foundation was founded by the Netscape-affiliated Mozilla Organization, and was officially launched on July 15,
2003. The organization is currently based in the Silicon Valley city of Mountain View, California, USA.
The Mozilla Foundation describes itself as "a non-profit organization that promotes openness, innovation and
participation on the Internet."[4] The Mozilla Foundation is guided by the Mozilla Manifesto, which lists 10
principles which Mozilla believes "are critical for the Internet to continue to benefit the public good as well as
commercial aspects of life."[5] The Manifesto has been translated into over 30 languages.

History
On February 23, 1998, Netscape created the Mozilla Organization to co-ordinate the development of the Mozilla
Application Suite.[6] When AOL (Netscape's parent) drastically scaled back its involvement with Mozilla
Organization, the Mozilla Foundation was launched on July 15, 2003 to ensure Mozilla could survive without
Netscape. AOL assisted in the initial creation of the Mozilla Foundation, transferring hardware and intellectual
property to the organization, employed a three-person team for the first three months of its existence to help with the
transition, and donated $2 million to the Foundation over two years.[7]
Initially, the remit of the Mozilla Foundation grew to become much wider than that of mozilla.org, with the
organization taking on many tasks that were traditionally left to Netscape and other vendors of Mozilla technology.
As part of a wider move to target end-users, the foundation made deals with commercial companies to sell CDs
containing Mozilla software and provide telephone support. In both cases, the group chose the same suppliers as
Netscape for these services. The Mozilla Foundation also became more assertive over its intellectual property, with
policies put in place for the use of Mozilla trademarks and logos. New projects such as marketing were also started.
With the formation of the Mozilla Corporation, the Mozilla Foundation delegated all their development and
business-related activities to the new subsidiary. The Mozilla Foundation now focuses solely on governance and
policy issues, though it also continues to oversee the projects that have not been "productized", such as Camino and
SeaMonkey. The Mozilla Foundation owns the Mozilla trademarks and other intellectual property, which it licenses
to the Mozilla Corporation. It also controls the Mozilla source code repository and decides who is allowed to check
code in.


Subsidiaries

Mozilla Corporation
On 3 August 2005, the Mozilla Foundation announced the creation of Mozilla Corporation, described as "a taxable
subsidiary that serves the non-profit, public benefit goals of its parent, the Mozilla Foundation, and that will be
responsible for product development, marketing and distribution of Mozilla products."[8] It also handles relationships
with businesses, many of which generate income. Unlike the Mozilla Foundation, the Mozilla Corporation is a
tax-paying entity, which gives it much greater freedom in the revenue and business activities it can pursue. The
majority of the revenues comes from Google Inc., which is the default search engine on Mozilla Firefox.

Beijing Mozilla Online Ltd
Beijing Mozilla Online Ltd [9] (Chinese: 北京谋智网络技术有限公司), a.k.a. Mozilla China, is a
wholly owned subsidiary of the Mozilla Corporation[10] with its headquarters in Beijing.

Financing
The Mozilla Foundation accepts donations as a source of funding. Along with AOL's initial $2 million donation,
Mitch Kapor gave $300,000 to the organization at its launch. The group has tax-exempt status under IRC 501(c)(3)
of the U.S. tax code, though the Mozilla Corporation subsidiary is taxable.
In 2006, the Mozilla Foundation received $66.8 million in revenues, of which $61.5 million is attributed to "search
royalties".[11]
The foundation has an ongoing deal with Google to make Google search the default in the Firefox browser search
bar and hence send it search referrals; a Firefox themed Google search site has also been made the default home page
of Firefox. The contract originally expired in November 2006. However Google renewed the contract until
November 2008 and again through 2011.[12] On 20 December 2011 Mozilla announced that the contract was once
again renewed for at least three years to November 2014, at 3 times the amount previously paid, or nearly $300
million annually.[13][14] Approximately 85% of Mozilla’s revenue for 2006 was derived from this contract. This
amounts to approximately US$56.8 million.[11]

People
The Mozilla Foundation Board of Directors has five members:[15]
• Mitchell Baker (Chair)
• Brian Behlendorf
• Brendan Eich
• Joichi Ito
• Bob Lisbonne
Originally, Christopher Blizzard had a seat on the board, but he moved to the Mozilla Corporation Board of
Directors when it was established; Joichi Ito joined the Mozilla Foundation board at that time. Bob Lisbonne and
Carl Malamud were elected to the board in October 2006.
The Mozilla Corporation also has a number of employees, many of whom worked for the foundation before the
establishment of the corporation.
The Mozilla project has traditionally been overseen by a committee known as mozilla.org staff; some individuals on
that committee later became Foundation or Corporation board members or employees.


Support for natural ecosystems
Mozilla is dedicated to preserving and promoting a healthy online space. As the community develops new versions
of Firefox and Thunderbird, park names are chosen as the code names for each product release.[16]

Donations
In 2006, after a request from Theo de Raadt of OpenBSD for funding from corporate entities which make a profit
through the use of OpenSSH in their packaged distributions, the Mozilla Foundation donated US$10,000 to de Raadt
and OpenBSD for OpenSSH development. The funds donated came from money earned through the income
provided by Google. While the target of this request were corporations such as Cisco, IBM, HP, and Red Hat (which
all sell operating systems containing OpenSSH but have not donated to its continued development before), the
Mozilla Foundation found that without OpenSSH, much of the work done by developers would be through insecure
and unsafe methods and thus gave the funds as a thank you.[17]
At the end of 2010, the Mozilla Foundation partnered with Knoxville Zoo in an effort to raise awareness about
endangered red pandas. Two red pandas (a.k.a. firefox) cubs born at the Knoxville Zoo have officially become a part
of the Mozilla community. The cubs are named Spark and Ember by online voters and Mozilla broadcasted a 24
hour live video stream of the cubs for several months.[18][19][20][21]

Entrance to downtown Mountain View office building currently home to both the Mozilla Foundation and the Mozilla Corporation

The Mozilla Corporation (abbreviated MoCo) is a wholly owned subsidiary of the Mozilla Foundation that
coordinates and integrates the development of Internet-related applications such as the Firefox and SeaMonkey web
browsers and the Mozilla Thunderbird email client by a global community of open-source developers, some of
whom are employed by the corporation itself. The corporation also distributes and promotes these products. Unlike
the non-profit Mozilla Foundation, and the Mozilla open source project, founded by the now defunct Netscape
Corporation, the Mozilla Corporation is a taxable entity. The Mozilla Corporation reinvests some or all of its profits
back into the Mozilla projects.[4] The Mozilla Corporation's stated aim is to work towards the Mozilla Foundation's
public benefit to "promote choice and innovation on the Internet."[5]
A MozillaZine article explained:
The Mozilla Foundation will ultimately control the activities of the Mozilla Corporation and will retain
its 100 percent ownership of the new subsidiary. Any profits made by the Mozilla Corporation will be
invested back into the Mozilla project. There will be no shareholders, no stock options will be issued
and no dividends will be paid. The Mozilla Corporation will not be floating on the stock market and it
will be impossible for any company to take over or buy a stake in the subsidiary. The Mozilla
Foundation will continue to own the Mozilla trademarks and other intellectual property and will license
them to the Mozilla Corporation. The Foundation will also continue to govern the source code
repository and control who is allowed to check in.[6]

Establishment
The Mozilla Corporation was established on August 3, 2005 to handle the revenue-related operations of the Mozilla
Foundation. As a non-profit, the Mozilla Foundation is limited in terms of the types and amounts of revenue. The
Mozilla Corporation, as a taxable organization (essentially, a commercial operation), does not have to comply with
such strict rules. Upon its creation, the Mozilla Corporation took over several areas from the Mozilla Foundation,
including coordination and integration of the development of Firefox and Thunderbird (by the global free software
community) and the management of relationships with businesses.
With the creation of the Mozilla Corporation, the rest of the Mozilla Foundation narrowed its focus to concentrate on
the Mozilla project's governance and policy issues. In November 2005, with the release of Mozilla Firefox 1.5, the
Mozilla Corporation's website at mozilla.com was unveiled as the new home of the Firefox and Thunderbird
products online.
In 2006 the Mozilla Corporation generated 66.8 million dollars in revenue and 19.8 million in expenses, with 85% of
that revenue coming from Google for "assigning [Google] as the browser's default search engine, and for
click-throughs on ads placed on the ensuing search results pages."[7][8]


Notable events
In March 2006, Jason Calacanis reported a rumor on his blog that Mozilla Corporation gained $72M during the
previous year, mainly thanks to the Google search box in the Firefox browser.[9] The rumor was later addressed by
Christopher Blizzard, then a member of the board, who wrote on his blog that, "it’s not correct, though not off by an
order of magnitude."[10] Two years later, TechCrunch wrote: "In return for setting Google as the default search
engine on Firefox, Google pays Mozilla a substantial sum – in 2006 the total amounted to around $57 million, or
85% of the company’s total revenue. The deal was originally going to expire in 2006, but was later extended to 2008
and will now run through 2011."[11] The deal was extended again another 3 years, until November 2014. In this latest
deal Mozilla will get another $900 million ($300 million annually) from Google, nearly 3 times the previous
amount.[12]
In August 2006, Microsoft posted a letter on Mozilla newsgroups[13] and offered to open up a new open-source
facility at its headquarters in Redmond, Wash., to Mozilla software engineers. Mozilla responded by accepting the
offer.[14]

The Mozilla Application Suite (originally known as Mozilla, marketed as the Mozilla Suite, and code named
SeaMonkey) was a cross-platform integrated Internet suite. Its development was initiated by Netscape
Communications Corporation, before their acquisition by AOL. It was based on the source code of Netscape
Communicator. The development was spearheaded by the Mozilla Organization from 1998 to 2003, and by the
Mozilla Foundation from 2003 until it was discontinued in 2006. It has been superseded by SeaMonkey Internet
suite, a community-driven Internet suite that is based on the same source code and continued to be developed with
newer Mozilla codebase.
The Mozilla Suite was composed of several main programs: Navigator (a Web browser), Communicator (Mozilla
Mail & Newsgroups), a Web page developer (Mozilla Composer), an IRC client (ChatZilla) and an electronic
address book. Also included were tools to synchronise the application with Palm Pilot devices, and several
extensions for advanced Web development including the DOM Inspector and Venkman (a JavaScript debugger).
Versions 6 and 7 of the Netscape suite were based on the Mozilla Suite. The last official version is 1.7.13, as Mozilla
Foundation is now focusing on the development of Firefox and Thunderbird. The Mozilla Suite is available under
the terms of the Mozilla project's tri-license, as free and open source software.


History and development
In March 1998, Netscape released most of the code base for its popular
Netscape Communicator suite under an open source license. The name
of the application developed from this would-be Mozilla, coordinated
by the newly created Mozilla Organization, at the mozilla.org Web
site. Although large parts of the original Communicator code,
including the layout engine and front-end related codes, were
abandoned shortly thereafter, the Mozilla Organization eventually
succeeded in producing a full-featured Internet suite that surpassed
Communicator in features, stability and degree of standards Startup screen of the Mozilla Application Suite
for Mac OS 9 featuring the Mozilla mascot
compliance.

Under the AOL banner, Mozilla Organization continued development of the browser and management of the Mozilla
source until July 2003 when this task was passed to the Mozilla Foundation. The Foundation is a non-profit
organization composed primarily of developers and staff from mozilla.org and owns the Mozilla trademark (but not
the copyright to the source code, which is retained by the individual and corporate contributors, but licensed under
the terms of the GPL and MPL). It received initial donations from AOL, IBM, Sun Microsystems, Red Hat, and
Mitch Kapor. However, all official ties with AOL were severed following the announcement of the end of the
Netscape Navigator browser and AOL's agreement to use Microsoft's Internet Explorer browser in future versions of
its AOL software. AOL has since announced it will be using Mozilla's Gecko layout engine.

According to the Mozilla development roadmap published on April 2, 2003, the Mozilla Organization planned to
focus development efforts on the new standalone applications: Phoenix (now known as Mozilla Firefox) and
Minotaur (now known as Mozilla Thunderbird). To distinguish the suite from the standalone products, the suite is
marketed as "Mozilla Suite" or the more lengthy "Mozilla Application Suite".
On March 10, 2005, the Mozilla Foundation announced that they would not release any further official versions of
the suite beyond 1.7.x. However, the Mozilla Foundation emphasized that they would provide infrastructure for
community members who wished to continue development. In effect, this means that the suite will still continue to
be developed, but not by the Mozilla Foundation itself. To avoid confusing organizations that still want to use the
Mozilla Suite, it was announced that the new, community-developed product would be named "SeaMonkey", with
version numbers that start at "1.0".

Features

Usability and accessibility
Mozilla supported tabbed browsing, which allows users to open multiple Web pages in the same browser window.
This feature was written with the popular MultiZilla [4] extension for Mozilla as a base. Mozilla also belonged in the
group of browsers who early on adopted customizable pop-up blocking.
The browser had a number of features which helped users find information. First, Mozilla had an incremental find
feature known as "find as you type". With this feature enabled, a user could simply begin typing a word while
viewing a Web page, and the browser automatically searched for it and highlighted the first instance found. As the
user typed more of the word, the browser refined its search.
Additionally, Mozilla supported the "custom keyword" feature. This feature allowed users to access their bookmarks
from the location bar using keywords (and an optional query parameter). For example, using a custom keyword, a
user could type "google apple" into the address bar and be redirected to the results of a Google search for "apple".
For the mail and newsgroup component, the built-in Bayesian e-mail spam filter could effectively filter out unwanted
e-mail spam after a period of training.


Customizability
Mozilla introduced the extension model, which was expanded and improved by Firefox and Thunderbird. Through
extensions (installed via XPInstall modules), users might activate new features, such as mouse gestures,
advertisement blocking, proxy server switching, and debugging tools.
One can view the extension system as a ground for experimentation, where one can test new functionalities.
Occasionally, an extension, or a part of it, became part of the official product (for example MultiZilla's tabbed
browsing feature eventually became part of the standard Mozilla).
Mozilla also supported a variety of themes/skins, which changed its appearance. Themes consisted of packages of
CSS and image files. The Mozilla Add-ons Web site offered many themes. Beyond adding a new theme, users could
customize its interface by adding and removing some of its buttons and toolbars.
Additionally, Mozilla stored most of its preferences in a list that users could access by typing about:config in the
address bar. Some preferences were only available through it, like turning on bookmark icons.

Standards support
The Mozilla Foundation took pride in Mozilla's compliance with existing standards, especially W3C Web standards.
Mozilla had extensive support for most basic standards at the time including HTML, XML, XHTML, CSS,
JavaScript, DOM, MathML, DTD, XSLT and XPath.
Mozilla also supported PNG images and variable transparency, (which Internet Explorer only supported fully in
version 7). Indeed, Internet Explorer's lack of support for PNG images has occasioned much debate, as many Web
developers wanted to move away from the old GIF format, which does not have the same capabilities and image
quality as PNG.
Mozilla had implemented most of CSS Level 2 and some of the not-yet-completed CSS Level 3 standard. It was
among the first browsers to pass the original Box Acid Test [5], although it doesn't fully pass the more rigorous
Acid2 test for HTML, CSS, and PNG standards support. Other browsers based on newer versions of Mozilla's core
technology, however, pass the Acid2 test.
The mail and newsgroup supported POP and IMAP. It also supported LDAP address completion. Both reading and
writing of HTML e-mails were supported. Mail files were stored in mbox format, and were thus portable.
The first version of the suite, i.e., the one that formed the basis of Netscape 6, did not support the blink element, thus
making it the only Netscape/Mozilla browser that has not supported the notorious tag that Netscape itself created.
Later versions of the suite supported the element as well as the marquee tag, originally created by rival Internet
Explorer.

Cross-platform support
Mozilla ran on a wide variety of platforms. Releases available on the primary distribution site supported the
following operating systems:
• Various versions of Microsoft Windows, including 95, 98, Me, NT 4.0, 2000, XP, Server 2003, and Vista.
• Mac OS X
• Mac OS 9 (discontinued after Mozilla 1.2.1, but an unofficial Mozilla 1.3.1 is available here [6]). However, an
updated branch of the Suite survives for the classic Mac OS in the form of Classilla.
• Linux-based operating systems using X.Org Server or XFree86
• OS/2, also known as Warpzilla[7]
Mozilla used the same format to store users' profiles (which contain their personal browser settings) even on
different operating systems, so a profile might be used on multiple platforms, as long as all of the platforms could
access the profile (e.g., the profile was stored on a FAT32 partition accessible from both Windows and Linux). This
functionality was useful for users who dual-boot their machines. However, it might occasionally cause problems,


especially with extensions.

Web development tools
Mozilla came with three Web development tools — a DOM Inspector, Venkman and JavaScript Console. The DOM
Inspector was not available in non-Mozilla browsers, and the JavaScript Console was more advanced than the
consoles available in non-Mozilla browsers. Venkman was a difficult to use but decent JavaScript debugger. These
were installed by default, though you could opt them out (except for the JavaScript Console) with the other install
options.

Security
Mozilla was designed with security in mind. Among its key features were the use of the sandbox security model,
same origin policy and external protocol whitelisting.
One key characteristic of Mozilla security was that its source code is visible to everyone. Proposed software changes
were reviewed by at least one other person, and typically "super-reviewed" by yet another, and once placed in the
software were visible for anyone else to consider, protest, or improve.
In addition, the Mozilla Foundation operated a "bug bounty" scheme: Users who reported a valid critical security bug
received a US$500 cash reward for each report and a Mozilla T-shirt. The purpose of this "bug bounty" system,
according to the Mozilla Foundation, was to "encourage more people to find and report security bugs in our
products, so that we can make our products even more secure than they already are". Anyone in the world could
report a bug. Also, access to the source code of Mozilla Firefox, internal design documentation, forum discussions,
and other materials that could be helpful in finding bugs were available to anyone.
The Mozilla Foundation has issued a security bugs policy to help contributors to deal with security vulnerabilities.
The policy restricts access to a security-related bug report to members of the security team until after Mozilla has
shipped a fix for the problem. This is intended to deter the exploitation of publicly-known vulnerabilities and give
the developers time to issue a patch. While similar to other "responsible disclosure" policies issued by companies
such as Microsoft, this policy is opposed to the full disclosure principle favored by some security researchers.
As of June 2005, Secunia had reported three unpatched vulnerabilities [8] in Mozilla with the most serious one
marked "less critical".

Market adoption and project end
From 1998 to 2004, the global usage share of Mozilla grew from a negligible amount to about 3%. Because of the
Foundation's plan to switch development focus to standalone applications such as Firefox and Thunderbird, many
new features and enhancements were not available for Mozilla. This, combined with the community marketing effort
named "Spread Firefox", drew more and more users away from Mozilla since late 2004, when Firefox 1.0 was
released. There were no official releases of the Mozilla Suite beyond version 1.7.13. As of 2008, Mozilla Suite usage
share was approximately 0.1%. SeaMonkey, a community-driven Internet suite that is based on the same source
code, is pursued by those that appreciated Mozilla's feature set.

Mozilla Thunderbird is a free,[7] open source, cross-platform email and news client developed by the Mozilla
Foundation. The project strategy is modeled after Mozilla Firefox, a project aimed at creating a web browser. On
December 7, 2004, version 1.0 was released, and received over 500,000 downloads in its first three days of release,
and 1,000,000 in 10 days.[8][9]

Features
Thunderbird is an email, newsgroup and news feed client. The vanilla version is not a personal information manager,
although the Mozilla Lightning extension adds PIM functionality. Additional features, if needed, are often available
via other extensions.

Message management
Thunderbird can manage multiple email, newsgroup and news feed accounts and supports multiple identities within
accounts. Features like quick search, saved search folders ("virtual folders"), advanced message filtering, message
grouping, and labels help manage and find messages. On Linux-based systems, system mail (movemail) accounts are
supported. A still unsolved problem regards the possibility to archive email messages on disk. When exporting a


message, by saving or dragging and dropping, the timestamp of the exported file given by Thunderbird is that of the
moment in which the file was exported. For archiving reasons it would be necessary that exported file had the
timestamp corresponding to the moment in which it was sent or received.

Junk filtering
Thunderbird incorporates a Bayesian spam filter, a whitelist based on the included address book, and can also
understand classifications by server-based filters such as SpamAssassin.[10]

Extensions and themes
Extensions allow the addition of features through the installation of XPInstall modules (known as "XPI" or "zippy"
installation) via the add-ons website which also features an update functionality to update the extensions. An
example of a popular extension is Lightning, which adds calendar functionality to Thunderbird.
Thunderbird supports a variety of themes for changing its overall look and feel. These packages of CSS and image
files can be downloaded via the add-ons website at Mozilla Add-ons [11].

Standards support
Thunderbird supports POP and IMAP. It also supports LDAP address completion. The built-in RSS/Atom reader can
also be used as a simple news aggregator. Thunderbird supports the S/MIME standard, extensions such as Enigmail
and support for the OpenPGP standard.
List of supported IMAP extensions: https://wiki.mozilla.org/MailNews:Supported_IMAP_extensions

File formats supported
• mbox – Unix mailbox format
• Mork – used for internal database
• SQLite – also used for internal database (since version 3)

Cross-platform support
Thunderbird runs on a wide variety of platforms. Releases available on the primary distribution site support the
following operating systems:[12]
• Windows
• Linux
• Mac OS X
• OS/2 and eComStation [13]
• OpenSolaris
• FreeBSD [14]
The source code is freely available and can be compiled to be run on a variety of other architectures and operating
systems.


Internationalization and localization
Thunderbird does not yet support SMTPUTF8(RFC 6531) or Email Address Internationalization.
With contributors all over the world, the client is translated into at least 52 languages, but client's addresses are
currently limited to ASCII local parts.[15]

Security
Thunderbird provides enterprise and government-grade security features such as SSL/TLS connections to IMAP and
SMTP servers. It also offers native support for S/MIME secure email (digital signing and message encryption using
certificates). Any of these security features can take advantage of smartcards with the installation of additional
extensions.
Other security features can be added through extensions. For instance, Enigmail offers PGP signing, encryption, and
decryption.
Optional security protections also include disabling loading of remote images within messages, enabling only
specific media types (sanitizer), and disabling JavaScript.
The French military uses Thunderbird and contributes to its security features, which are claimed to match the
requirements for NATO's closed messaging system.[16]

History
Originally launched as Minotaur shortly after Phoenix (the original name for Mozilla Firefox), the project failed to
gain momentum. With the success of the latter, however, demand increased for a mail client to go with it, and the
work on Minotaur was revived under the new name of Thunderbird, and migrated to the new toolkit developed by
the Firefox team.
Significant work on Thunderbird restarted with the announcement that from version 1.5 onwards, the main Mozilla
suite would be designed around separate applications using this new toolkit. This contrasts with the previous
all-in-one approach, allowing users to mix and match the Mozilla applications with alternatives. The original Mozilla
Suite continues to be developed as SeaMonkey.
On December 23, 2004, Project Lightning was announced which tightly integrated calendar functionality
(scheduling, tasks, etc.) into Thunderbird, and which is now available as a downloadable extension.
On October 11, 2006, Qualcomm and the Mozilla Foundation announced that "future versions of Eudora will be
based upon the same technology platform as the open source Mozilla Thunderbird email program."[17] The project is
code-named Penelope.
In late 2006, Debian rebranded Thunderbird as Icedove due to trademark and copyright reasons. This was the second
product to be rebranded.[7][18]
On July 26, 2007, the Mozilla Foundation announced that Thunderbird would be developed by an independent
organization, because the Mozilla Corporation (a subsidiary of the foundation) was focusing on Mozilla Firefox
development.[19]
On September 17, 2007, the Mozilla Foundation announced the funding of a new internet communications initiative
with Dr. David Ascher of ActiveState. The purpose of this initiative was "to develop Internet communications
software based on the Thunderbird product, code and brand".[20]
On February 19, 2008, Mozilla Messaging started operations as a subsidiary of the Mozilla Foundation responsible
for the development of email and similar communications. Its initial focus was on the then upcoming version of
Thunderbird 3. Alpha Preview releases of Thunderbird 3 were codenamed "Shredder".
On April 4, 2011, Mozilla Messaging was merged into the Mozilla Labs group of the Mozilla Foundation.[21] As of
24 October 2011, the current version is Thunderbird 7.0.1.[22] Thunderbird 3 no longer supports versions of


Windows prior to Windows 2000 (i.e., Windows 95, 98, ME and NT) and Mac OS X versions prior to 10.4 Tiger.[23]
On July 6, 2012, a confidential memo from Jb Piacentino, the Thunderbird Managing Director at Mozilla, was
leaked and published to TechCrunch.[24] The memo indicates that Mozilla will be moving some of the team off the
project and further development of new features will be left up to the community. The memo was slated for release
on the afternoon of July 9, 2012, pacific time.
Thunderbird development releases occur in three stages, called Beta, Earlybird and Daily, which correspond to
Firefox's Beta, Aurora and Nightly stages. The release dates and Gecko versions are exactly the same as Firefox; for
example, Firefox 7 and Thunderbird 7 were both released on September 27, 2011, and were both based on Gecko
7.0.

Add-on (Mozilla) 64

Add-on (Mozilla)
Add-ons are installable enhancements to the Mozilla Foundation's
projects, and projects based on them. Add-ons allow the user to add or
augment application features, use themes to their liking, and handle
new types of content.

Types of add-ons

Extensions
Extensions can be used to modify the behavior of existing features to
the application or add entirely new features. Extensions are especially
popular with Firefox, because Mozilla developers intend for the
browser to be a fairly minimalistic application in order to reduce
software bloat and bugs, while retaining a high degree of extensibility,
so that individual users can add the features that they prefer.

Featured Firefox addons from the official page
Extension technologies[2] [1]

• CSS (Cascading Style Sheets)
• DOM (Document Object Model) – Used to change XUL in real-time or to edit HTML that is currently loaded
• JavaScript – The primary language of Mozilla browsers
• XPCOM (Cross-Platform Component Object Model)
• XPConnect
• XPI (Cross-Platform Installer)
• XUL (XML User Interface Language) – Used to define the UI (User Interface) and interaction with user.
• Mozilla Jetpack – a development kit aiming to lower the learning curve and development time for making
add-ons.

Uses

Interface changes
Some extensions are used to change the interface of the application. These are not to be confused with personas,
which are a theme management feature. For example, several add-ons exist to change the color of the Firefox button,
such as ColorizedButton. There is also an add-on which moves the menu bar to where the window title normally is
on windows machines.

Adding features
Extensions are generally used to add functions to the application. Examples of functions which an extension might
add include RSS readers, bookmark organizers, toolbars, website-specific client programs, FTP, e-mail, mouse
gestures, proxy server switching, or developer tools. Many Firefox extensions implement features formerly part of
the Mozilla Suite, such as the ChatZilla IRC client and a calendar.

Add-on (Mozilla) 65

Modifying how the user views web pages
Many extensions can change the content of a webpage as it is rendered. For example, Adblock extensions can
prevent the browser from loading images which are advertisements. Another popular extension, Greasemonkey,
allows the user to install scripts which modify a targeted subset of webpages on the fly in a manner which is the
programmatic complement to user style sheets.[3]

Other uses
Extensions also exist for frivolous, humorous or satirical purposes. Some allude to historical features of the Firefox
browser, for example restoring the "delicious delicacies" placeholder text removed in Firefox 0.9, or generating
random browser names to allude to the Firefox name changes.

Plugins
Common plugins include Acrobat Reader, Flash Player, Java, Quicktime, RealPlayer, Shockwave, and Windows
Media Player.

Compatibility and updates
Add-ons contain files with XML metadata utilized by the mechanism which controls add-on installation. Among
other things, this file identifies maximum and minimum versions of a Mozilla project application with which the
add-on may be used. If an attempt is made to install the add-on on a version outside of this range, it will install but
will be disabled. Add-ons will often work outside of their compatibility range, and indeed some advanced users edit
the metadata file to allow the released version of the add-on to run on their install. It is even possible to override the
compatibility check using various extensions.
The success of a formal compatibility check is no guarantee the add-on will work, however.
The add-on manager periodically checks for updates to installed add-ons, although checks for updates can be
manually initiated by the user. By default, the update service will look for updates at Mozilla Add-ons, but if the
developer includes provisions to check elsewhere, the service will do so.
