MOST USEFUL FIREFOX ADDONS

If you're going to get just one from this list, make it this one. WebMail Notifier is an email consolidator that alerts you whenever you receive new mail from your numerous accounts. In previous years, this free service was limited to Yahoo! Mail and Gmail, but it has been upgraded recently to accommodate Hotmail and POP3 servers.

Print Screen is so 1990s, that's why you have to up your game especially when you're capturing websites. Screengrab allows you to take snapshots of whole Web pages and to save them in a variety of picture formats. No more tedious cutting and pasting here!

Persona is a new feature in Firefox 3.6, and Personas Plus is just the add-on to help you personalize the heck out of your browser. This add-on is a collection of over 60,000 themes/wallpapers/skins (call it whichever way you like) that are guaranteed to make Firefox look even foxier.

As its name suggests, this free software gives you some well-deserved peace of mind whenever you're surfing the Web. AdBlock Plus filters ads, photos, malware, plus a bunch of other potentially harmful junk on the Internet that are out to take down your precious PC. Nearly 81 million Firefox users have downloaded it, making it one of the most popular add-ons ever.

Note: Downloading YouTube clips is illegal

Note 2: You don't care

Now that we got those 2 out of the way, it's enough that we say that Easy YouTube Video Downloader is, in fact, an easy way to download YouTube videos. It may not be as easy as using 3ouTube, but it is more versatile and it lets you download videos in full 1080p HD or even in MP3 format (audio only, obviously).

If you love Safari 4's Top Sites home screen and you would like to have the same feature available on your Firefox, this add-on is just the ticket. It doesn't stop there, though. There are other pane transition/arrangement settings that you could choose from. Some mimic Windows' Aero and Apple's Cover Flow. Sweet!

A nearly-all-in-one translator that gives your browser the power to understand the following languages (Jejenese not included): Albanian, Arabic, Bulgarian, Catalan, Chinese (Simp.), Chinese (trad.), Croatian, Czech, Danish, Dutch, English, Estonian, Filipino, Finnish, French, Galician, German, Greek, Hebrew, Hindi, Hungarian, Indonesian, Italian, Japanese, Korean, Latvian, Lithuanian, Maltese, Norwegian, Polish, Portuguese, Romanian, Russian, Serbian, Slovak, Slovenian, Spanish, Swedish, Thai, Turkish, Ukrainian, and Vietnamese.

We love TV and we love the Internet, so it's good that somebody decided to combine both in a simple toolbar. TV-FOX lets you watch from hundreds of online channels from all over the world. It's no Google TV, though, as channels are subject to availability and they're not 100% guaranteed to be on-air all the time.

On a more boring serious note, developer tools do exist in the add-ons repository. By far, one of the more popular is Firebug. It's a tool that helps developers "edit, debug, and monitor CSS, HTML, and JavaScript live on any Web page." Thousands of hardcore nerds have expressed their gratitude to the alpha nerds creators, and the proof of its usefulness is in the download count.

For those who just can't shake off Facebook, here's an add-on that will help you cave in completely. Facebook Toolbar seamlessly integrates the popular social-networking hell site into Firefox. With it installed, you get instant notifications from everything that goes on with your account. Wave bye-bye to productivity!
