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.

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.
Works with Google products
All your favorite Google tools (like Gmail and Docs) work seamlessly in the Firefox Browser.
Firefox is available on all your devices; take your tabs, history and bookmarks with you. All you need is a Mozilla account and you’ll get access to syncing and more Mozilla products.
Picture-in-Picture
From watching a web tutorial to keeping an eye on your favorite team, your video follows you while you multitask.
