Mozilla Firefox, developed by the Mozilla Foundation, was first released in 2002 as an open-source alternative to Internet Explorer. Built on the Gecko rendering engine, it introduced features like tabbed browsing, extensions, and a focus on web standards. Over time, Firefox has undergone significant updates, including the Quantum overhaul in 2017, which improved performance and efficiency.
Firefox is available on Windows, macOS, Linux, Android, and iOS, with a strong emphasis on customization and independent development. It supports modern web technologies and continues to evolve with regular updates. Mozilla maintains Firefox as part of its mission to promote an open and accessible web.
