This document summarizes three Mozilla tools for webmaking: Thimble, Hackasaurus, and Popcorn. Thimble makes creating webpages simple within a browser by allowing users to write HTML and CSS and preview changes instantly. Hackasaurus similarly allows changing and sharing webpages within a browser using tools like X-Ray Goggles. Popcorn enables interaction between users and web content like video by allowing real-time engagement through tools like Popcorn.js. All three tools aim to make webmaking accessible through the browser.
