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.
Put Firefox on all your devices
Take your privacy with you everywhere. Firefox Browsers for iOS and Android have the same strong privacy settings to block trackers from following you around the web, no matter where you are.

Backed by the non-profit that puts people first

Your privacy comes first
As the internet grows and changes, Firefox continues to focus on your right to privacy — we call it the Personal Data Promise: Take less. Keep it safe. No secrets. Your data, your web activity, your life online is protected with Firefox.

Firefox Beta is the build for those who like a little bit of jeopardy, but who don’t want to risk everything by trying out Firefox Developer, the early alpha build of Firefox. Firefox Beta gives you a sneak peek at the next version of Firefox six weeks ahead of its final release, offering a relatively stable build that’s not quite ready for primetime, but still pretty solid.
Whereas Firefox Developer installs as a completely separate application alongside your existing Firefox installation, Firebox Beta will replace the stable build. Should you subsequently wish to go back to the safer version, you’ll need to manually download the stable version and install it over the top of the beta build.
Confirm which build you have by selecting About Firefox from the Firefox menu or button (it’s inside the Help menu if using the Firefox button).
Verdict:
Check out the next version of Firefox before it's released.
