Firefox OS is a Linux kernel-based mobile operating system designed for smartphones, tablets, and smart TVs.
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.
Since that time, developers have added features to make the system more competitive with well-established mobile operating systems such as Android and iOS.
