Opening a lot of tabs in Firefox can compress them so small that you don't know what each one is. This CSS tweak will enlarge the active tab, so you can at least always see what page you're working on.

The swishing tab animations in Firefox are pretty and all, but if you'd rather your computer concentrate on actual page loading rather than eye candy, there's a very simple about:config fix.

Firefox 4+ (Windows only): Usually, changing your Firefox browser's looks requires a CSS tweak, an about:config switch or specialised downloads. Stratiform is an all-in-one add-on that offers a variety of button, toolbar and other visual element switches. Try out new themes and switch back without any hassle.

You've probably heard a lot about Firefox 4's new interface, speed and feature improvements, but many of you have already left it for Chrome. Here's why Firefox's newest version is worth another look, even if you're a diehard Chrome user.

Android/Maemo: Android has a lot of great browser alternatives, but today Mozilla released the final version of Firefox 4 Mobile, which brings tabbed browsing, add-ons and serious synchronisation power to your phone.

You may notice that when you mouse over a link in Firefox, the URL preview in the status bar is trimmed down to save space. If you'd rather see the whole URL, you can do so with a simple CSS tweak.

Firefox 4 no longer asks you if you want to save your tabs whenever you quit the browser. If you want to restore this behaviour, all you need is a little about:config action.

If you have a multitouch trackpad, you may be used to zooming in and out of web pages in your browser. Unfortunately, Firefox 4 disables them by default. Here's how to get them back.

Firefox 4 has a lot going for it, but many of you (and us) mentioned that its UI has a few quirks that are a little annoying. Here's how to fix some of the worst offenders.

It has been quite a month for browsers, with Internet Explorer and Firefox both dropping big new versions, and Chrome and Opera continuing their regular improvements. We tested all these browsers' startup and tab-loading times, JavaScript powers, and memory use for your fast-minded enjoyment. Update: With 32-versus-64-bit IE 9 results.

Android/Maemo: With most bugs squashed and all its features in place, Firefox Mobile is looking like a nice alternative to the standard Android browser. It's not neck-and-neck in speed, but it's not slow, either. And the add-ons, desktop Firefox syncing, and better tabbed browsing are pretty intriguing.

Windows/Mac/Linux: The latest version of Firefox drops today, and it's got a lot going for it, including a more minimalistic interface, synchronisation and a serious speed increase. Here's what you have to look forward to in Firefox 4.

Firefox 4 is slated for an official release tomorrow, but impatient users can already grab the update from Mozilla's FTP servers now.

Firefox 4 on Windows: One of the longest-running complaints among the anti-Firefox crowd is that it's slow. One Mozilla developer has set out to fix part of this problem by making Firefox start up twice as fast in Windows with a simple add-on.

Firefox only: The previously mentioned BarTab extension lightens Firefox's memory load and prevents crashes—in other words, it's a great add-on. But the latest Firefox 4 betas, and presumably the final release, can do most of that with an about:config switch.

Windows/Mac/Linux: Firefox 4 Beta 7 is out, and it's an impressive preview of the final release. Mozilla has let loose the JaegerMonkey engine, enabled hardware graphics acceleration on Windows and Mac, and integrated Sync and the awesome Panorama/"Tab Candy".
