A complete, standalone operating system developed for the open Web with a primary focus as an open source mobile OS for mobile and tablet devices. Mozilla's Firefox OS project started out under the name of Boot to Gecko and, like Google's Chrome OS platform, is based on the Linux operating system at its core.
The Firefox OS emphasizes HTML 5 technology to go along with device capabilities like SMS and Bluetooth support. It's also optimized for low-end hardware and will be provided to manufacturers for free, helping these companies produce mobile devices that balance a high degree of functionality with low cost. The first batch of mobile devices running Firefox OS is expected to debut in early 2013.
