Firefox 21.0

Download Firefox 21.0, the most popular browser in the World, used by millions of people. It offers great security, privacy, and protection against viruses, spyware, malware, and it can also easily block pop-up windows. The latest version is highly customizable, supports add-ons and extensions, and each browser profile can be configured with different settings. Firefox offers:

Browsing Made Easy
Get to your favorite sites quickly – even if you don’t remember the URLs. Type your term into the location bar (aka the Awesome Bar) and the autocomplete function will include possible matches from your browsing history, bookmarked sites and open tabs.

High Performance
With faster start-up times, rapid graphics rendering and improved page load speed, the latest version of Firefox is full of major performance improvements you’ll notice instantly.

Advanced Security
Want to be extra sure about a site’s legitimacy before you make a purchase? Click on its favicon for an instant identity overview. Another click digs deeper: how many times have you visited? Are your passwords saved? Check up on suspicious sites, avoid Web forgeries and make sure a site is what it claims to be.

Powerful Personalization
The Add-ons Manager has been redesigned to let you discover and install add-ons without ever leaving Firefox. Browse ratings, recommendations, descriptions and pictures of the add-ons in action to help you make your selection.

The Cutting Edge
Site authors and developers will love Firefox’s new and enhanced functionalities. If creating advanced content and applications gets you excited, Firefox is the best browser choice.

Universal Access
Firefox supports open font formats like WOFF, TrueType and OpenType, meaning site designers are no longer limited to a select handful of web-ready fonts as they create their sites.
