How Firefox compares to other browsers

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.

How we compare to other browsers

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.

Review system requirements

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.

Do it all with Firefox

Make Firefox your own

  • Extensions for every interest

    From security to news to gaming, there's an extension for everyone. Add as many as you want until your browser is just right.

  • Change up your look

    Go from light mode to dark mode depending on your mood or preference, or liven things up with a custom theme (rainbow unicorn, perhaps).

  • Tweak your settings

    There's no need to settle. Change up the new tab page, search bar, bookmarks and more to explore the internet the way you want.

Backed by the non-profit that puts people first

Challenging the status quo since 1998

Firefox was created by Mozilla as a faster, more private alternative to browsers like Internet Explorer, and now Chrome. Today, our mission-driven company and volunteer community continue to put your privacy above all else.

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.

Keep all your favorite browser features — and discover new ones.

Works with Google products

All your favorite Google tools (like Gmail and Docs) work seamlessly in the Firefox Browser.

Sync your devices

Firefox is available on all your devices; take your tabs, history and bookmarks with you. All you need is a Firefox account.
