Description

Firefox is a free web browser developed by the non-profit Mozilla Foundation. It offers comprehensive tracking protection, a powerful extension management system, and respects user privacy. Firefox supports all modern web standards, provides integrated password management with Firefox Lockwise, and enables synchronization across multiple devices. As one of the few browsers with its own engine (Gecko), Firefox is an important guarantor of browser diversity on the web.
