Firefox is an open-source web browser which provides excellent browsing speed, rich suite of customization options to personalize your daily Internet sessions, clean navigation mode, as well as extensions provided by third-party developers for adding extra functions.

Mozilla Firefox is a fast, light and tidy open source web browser. At its public launch in 2004 Mozilla Firefox was the first browser to challenge Microsoft Internet Explorer’s dominance. Since then, Mozilla Firefox has consistently featured in the top 3 most popular browsers globally. The key features that have made Mozilla Firefox so popular are the simple and effective UI, browser speed and strong security capabilities. The browser is particularly popular with developers thanks to its open source development and active community of advanced users.

In time for the release of the next Extended Support Release for Firefox comes a new Policy Engine that Mozilla has been working on. Designed specifically for deployment in Enterprise environments, the new engine can be used in home environments as well for the most part. You can download policy template files from Mozilla's GitHub website. It is likely that they will be offered on the official Firefox ESR website as well.

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.

30% lighter than Chrome
Less memory usage means more space for your computer to keep running smoothly. Your other programs will thank you.

Smooth browsing
Whether you’ve opened 10 or 1000, switching between tabs is faster than ever with Firefox’s new, responsive engine.

Switch from Chrome to Firefox in just a few minutes
Switching to Firefox is fast, easy and risk-free. Firefox imports your bookmarks, autofills, passwords and preferences from Chrome.

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.

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.
