Firefox OS is the new mobile operating system developed by Mozilla, based on Linux and Firefox's powerful Gecko rendering engine.
Firefox OS is open source and therefore free from proprietary technology, while still providing the power to allow application developers to create excellent products. In addition, it's flexible and capable enough to make the end user happy.
For Web developers, the most important part to understand is that the entire user interface is a web app capable of displaying and launching other Web apps. Any modifications you make to the user interface and any applications you create to run on Firefox OS are web apps created using HTML, CSS, and JavaScript, albeit with enhanced access to the mobile device's hardware and services.
From a product perspective, Firefox OS is Mozilla's (and our OEM partner's) branding and support services applied on top of Boot to Gecko (B2G), which is the operating system's engineering codename. Boot to Gecko is developed by a team of engineers inside Mozilla plus many external contributors from the wider Mozilla/open source community.
