BSEditor: The Fastest firefox browser

Yet

Things MOVE quickly online, and we’ve beefed up the engine that runs Firefox to make sure you can keep up: Firefox 3.6 is more than twice as fast as Firefox 3, and ten times as fast as Firefox 2.* As a result, Web applications like email, photo sites and your favorite social networks will feel snappier and more responsive.

We’ve been working hard to make sure Firefox 3.6 brings you the best of the Modern web. With new features like Private Browsing, tear-off tabs and enhancements to the Awesome Bar, plus major performance enhancements, you’ll enjoy life on the cutting edge.
