Reviewed by: Seth Rosenblatt on June 30, 2009

No longer a fledgling upstart, Firefox 3 is full-featured, lightning fast, and an able foe for both the big-dog competitor Internet Explorer and competitors nipping at its heels. Firefox's killer add-ons remain strong, and the latest update makes version 3.5 about two times faster than version 3. However, competition is strong and it can no longer be said that Firefox is the fastest browser available.

Several notable improvements in the latest revamp keep Firefox abreast of current browsing tech. Along with Mozilla's new TraceMonkey JavaScript engine that renders Web applications faster on Firefox than ever before, there have also been improvements to the layout engine Gecko for faster page rendering. The new Private Browsing brings a feature to Firefox that competitors have had for a while: the capability to turn off cookie and history logs. Users also have more granular control over cookies, history, and bookmarks in version 3.5 via the redone Clear Recent History option under Tools. Geolocation courtesy of Google has been activated by default in Firefox, so that generic searches such as "city hall" will come closer to pegging the government offices nearest you.

Web developers should be excited about expanded support for HTML5 local storage, downloadable fonts, and native support for OGG-formatted embedded video. ICC profiles, SVG transforms, CSS media queries, native JSON support, and Web worker threads also get lots of love from v3.5. There's no doubt that Firefox 3.5 is a must-have, but it's an update that's more about keeping the browser current rather than blazing new trails.

Publisher's description

Mozilla Firefox is a fast, full-featured Web browser. Firefox includes pop-up blocking, tab-browsing, integrated Google search, simplified privacy controls, a streamlined browser window that shows you more of the page than any other browser and a number of additional features that work with you to help you get the most out of your time online.

Firefox 3.5 is based on the Gecko 1.9.1 rendering platform, which has been under development for the past year. Firefox 3.5 offers many changes over the previous version, supporting new web technologies, improving performance and ease of use, and adding new features for users: It is now available in more than 70 languages, includes a Private Browsing mode, better performance and stability with the new TraceMonkey JavaScript engine, the ability to provide Location Aware Browsing using web standards for geolocation, support for native JSON, and web worker threads, support for new web technologies such as: HTML5 < video > and < audio > elements, downloadable fonts and other new CSS properties, JavaScript query selectors, HTML5 offline data storage for applications, and SVG transforms.
