About the software

Mozilla Firefox, or simply Firefox, is a free and open-source web browser developed by the Mozilla Foundation and its subsidiary, the Mozilla Corporation. It uses the Gecko rendering engine to display web pages, which implements current and anticipated web standards.

Get all the speed and tools with none of the invasions of privacy. Firefox Browser collects so little data about you, we don’t even require your email address to download. That’s because unlike other browsers, we have no financial stake in following you around the web.

Ads are distracting and make web pages load slower while their trackers watch every move you make online. The Firefox Browser blocks most trackers automatically, so there’s no need to dig into your security settings.

Available in over 90 languages, and compatible with Windows, Mac and Linux machines, Firefox works no matter what you’re using or where you are. Make sure your operating system is up to date for the best experience.

The main features of Mozilla Firefox are:

  • Search smarter, faster
  • Boost your productivity
  • Stream, share and play
  • Protect your privacy
  • Secure your personal info
  • Customize your browser
