Mozilla discontinued support for Firefox OS in February 2016.

Firefox OS (also known as ) is an open source HTML5 based operating system developed for mobile devices by the Mozilla Corporation. Firefox OS is designed to run apps that are implemented in HTML, JavaScript, and CSS. The operating system also supports syntax like WebGL. It's constructed with three main components: Gaia, Gecko and Gonk. Together, they enable the power of Web technologies in your hands on a mobile device.

Gaia (Tag ) is the user interface layer for Firefox OS devices; it is a collection of HTML5 applications and APIs that implement system functions and applications like email, calendar, and OS settings.

Gecko (Tag ) is the layer of Firefox OS that provides the same open web standards implementation used by applications like Firefox and Thunderbird. This layer is where the magic happens: it's responsible for HTML, CSS and JavaScript rendering as well as proxying the JavaScript APIs to Gonk.

Gonk is the lower level operating system layer underneath Gecko. This consists of a Linux kernel and a hardware abstraction layer to which Gecko communicates.
