The operating system is developed by the open source community of the Mozilla Foundation, best known for the Firefox browser. Design and development are based entirely on open standards and non-proprietary technologies.
The first version of Firefox OS, released in mid-2013, was created for low-end phones to make them more accessible for people with limited means.

Alcatel, Huawei, LG, Nexus and ZTE are among the vendors that have released Firefox OS devices.
Firefox OS was called Boot to Gecko (B2G) in the initial development project.
