Firefox 3.5 officially released

Things move quickly online, and we’ve beefed up the engine that runs Firefox to make sure you can keep up: Firefox 3.5 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.
