Do what you do online.
Firefox Browser isn’t watching.

We block the ad trackers. You explore the internet faster.

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.

Firefox is for everyone

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.
