Mozilla recently released the first beta version of Firefox 4, the next iteration of the world's second most popular browser (after Internet Explorer). The new Firefox offers the usual under-the-hood tweaks you'd expect, such as improved security and better page rendering, and it also supports WebM, Google's new open video standard project. But more important to the average user, Firefox 4 offers a refreshed layout and appearance.
Taking a cue from Google Chrome, Firefox 4 beta now has the browser tabs pointing upward by default instead of hanging down from the top of the window. This is a great addition to Firefox, as it helps to maximize screen real estate for the Web page you're viewing. Mozilla says that this feature is available only for the Windows beta right now, but that it will be rolled out to the Mac and Linux versions in the future.
If tabs on top are not your thing, you can switch back to the more traditional Firefox tab layout by right-clicking the toolbar and deselecting the Tabs on top option. In Windows Vista and Windows 7, you can also go to the Firefox button on the upper-left side and select Customize, Tabs On Top.
The bookmarks menu has moved to a new bookmarks button on the upper right. Though the bookmarks layout has changed, the functionality is the same: To access your bookmarks, just click the star and select an item from the drop-down menu.
To access the switch-tabs function, just place your cursor in the Awesome Bar (that's the URL entry field for you Firefox newbies) and start typing name of the site or page you want to access. The Awesome Bar will start showing you a few options for past and current sites. One of the top options should be the tab you're looking for, and will be marked as 'Switch to tab' (see the screenshot). Just select that option and press Enter, and Firefox will switch to the tab for you.
In addition to the obvious new user features, Firefox 4 beta 1 also has a few added features under the hood. For starters, Mozilla has introduced crash protection for your Flash, QuickTime, and Silverlight plug-ins; this means that if the Flash Player crashes in one tab, for instance, it won't take the entire browser down with it.
Firefox 4 beta is also getting more HTML 5 capability, including the ability to display CSS Transitions, such as a Web page background that gradually shifts from white to black.
Mozilla has bumped up the privacy protection, as well, by closing a loophole that could allow a malicious script to sort through your browser history, exposing you to identity theft.
Overall, Firefox 4's new look and added features seem promising, and it will be interesting to see what other features Mozilla adds to future beta releases of Firefox 4. Keep in mind, though, that the Firefox 4 beta is a work in progress, and you may have to endure a few unexpected bugs and crashes. If you'd rather not deal with the headache, you might want to wait for the official launch of Firefox 4, which is scheduled for later this year.
