30% lighter than Chrome
Less memory usage means more space for your computer to keep running smoothly. Your other programs will thank you.
Whether you’ve opened 10 or 1000, switching between tabs is faster than ever with Firefox’s new, responsive engine.
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.
