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.

Compare Firefox to:
Firefox Chrome Microsoft Edge Safari
Blocks third-party tracking cookies Yes Yes Yes Yes Yes
Autoplay blocking Yes Yes No Yes Yes
Blocks social trackers Yes No Yes Yes No
OS availability Yes Yes No No Yes
In-browser screenshot tool Yes Yes Yes No Yes
Master Password Yes No Yes No Yes

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.

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.

Facebook Container

Download this browser extension to stop Facebook (and Instagram) from tracking you around the web.

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.

Screenshots

Grab a high-resolution image of anything online with our screenshot tool built right in the browser

Enhanced Tracking Protection (ETP)

Firefox automatically blocks many third party trackers from collecting and selling your web activity.

Picture-in-Picture

From watching a web tutorial to keeping an eye on your favorite team, your video follows you while you multitask.
