1. The document discusses Firefox OS and its use in Internet of Things applications using Raspberry Pi devices. 2. Firefox OS provides low level APIs that allow access to hardware such as GPIO pins, which can then be used to control devices like LEDs through JavaScript code. 3. A custom version of Firefox OS called JanOS has been created specifically for running on Raspberry Pi devices without a display.
