Firefox OS is a new mobile operating system, developed by Mozilla, and based on Linux and the Gecko engine that powers Firefox.
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.
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.
