A powerful, new engine that’s built for rapidfire performance.
Better, faster page loading that uses less computer memory.
Gorgeous design and smart features for intelligent browsing.
Now 2x faster
Crazy powerful browser engine? Check. Less time waiting around for pages to load? Also, check. Firefox Quantum is twice as fast as Firefox was before.
Whether you’ve opened 10 or 1000, switching between tabs is faster than ever with Firefox’s new, responsive engine.
Seriously Private Browsing
The most powerful private browsing mode with added tracking protection.
Firefox blocks online trackers while you browse and won’t remember your history after you’re done.
Some ads have hidden trackers that follow you online. Rude. We know. That’s why our powerful tool stops them cold.
Faster Page Loading
By blocking some ads and scripts that bog down browsing, pages load up to 44% faster. Now that’s a win-win.
Customize Firefox with thousands of extensions like LastPass, uBlock Origin, Evernote and more.
Make over Firefox to suit your mood! Choose a new look from our theme categories or create your own.
Sync your devices
Seamlessly access passwords, bookmarks and more. Plus, use our Send Tabs feature to instantly share open tabs between desktop, mobile and tablet.
Browse for good
