The Good Firefox 3 touts faster rendering, vastly reduced use of system resources, clever new data-mining tools for your bookmarks and browser history, and more security features than any other browser.

The Bad Firefox 3 will no longer support Windows 95, 98, and Me; same with Mac OS X, versions 10.2 and earlier.

The Bottom Line If only for the speed, lightness of being, and security alone, Firefox remains our Editors' Choice for best Internet browser.

After months of testing, Firefox 3 (code name Gran Paradiso) is available for download from Mozilla. With its new Gekko 1.9 engine, the browser rocks, rendering pages faster and uses fewer system resources overall. As with any new browser, some add-ons created for Firefox 2 may not work, but give them time. Firefox 3 touts faster rendering, a vastly reduced use of system resources, and clever new data-mining tools for your bookmarks and browser history. Most notable is that Firefox 3 includes many security-related features baked right in, such as the best of breed antiphishing protection, making Firefox the most secure browser on the market today. If you haven't already tried Firefox, what are you waiting for? Firefox 3 remains our Editors' Choice over Microsoft Internet Explorer and Opera. See our slide show of Firefox 3's basic features, and its various security features.

Firefox 3 is free, and available on a variety of operating systems: Windows, Mac, and Linux. There are also a wide variety of localized language versions, including Basque and Byelorussian. Unlike IE 7, Firefox 3 does not require a system reboot.

The interface is the same in some places, but different in others. Placement of buttons hasn't changed, but the icons are new. Firefox 3 now provides a native look and feel (for example, the Linux version matches the Linux user interface), and smooth scrolling of open browser tabs. What will draw the eye are more icons near and within the address bar itself. A company logo, if available, will appear before the URL; after the URL there's the new one-click bookmark star and the familiar RSS icon. Other tweaks include those to the Password manager, Add-Ons manager, and Download manager.

Returning within Firefox 3 are several core features, such as Sessions Restore, built-in spell checking, integrated search, pop-up blocker, clear private data, and automated behind-the-scenes updates.

Most exciting among the brand new features is the improved rendering speed thanks to the new Gekko 1.9 engine. Firefox 3 passes the Acid2 Browser Test, along with Safari 3 and Opera 9. The test, designed by the Web Standards Project, is designed to encourage designers to follow HTML and CSS 2.0 specifications. Currently Internet Explorer 7 does not pass, but Microsoft says Internet Explorer 8 is expected to follow Web specifications.

The Gekko 1.9 rendering engine will, however, introduce some inconveniences. Firefox 3 will no longer support Windows 95, 98, and Me; the same with Mac OS X, versions 10.2 and earlier. There will also be numerous changes made to the Document Object Model (DOM) within Gekko 1.9 that will affect developers more than users. Also, there will be changes in the way Firefox renders frames within its display and the way object tags are handled, as well as changes in event threading.

For a user, the project known as Places is worthy of praise, as it creates a light database of history, bookmarks, and tags within the browser that can be searched, sorted, and organized. How you access the database gives rise to many new features within Firefox 3.
