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.

Smooth browsing

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.

Private Browsing Firefox blocks online trackers while you browse and won’t remember your history after you’re done.

Tracking Protection 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.
