Back in January, I wrote a post that shared some of my favorite add-ons for Firefox, the over best Internet browser today. I am posting a revisit on the matter. I like to run a lean browser, so I don’t like to install too many that might slow me down. There are hundreds, if not, thousands of extensions you can install in Firefox. I have tried plenty of them and a most of them are cool in their own way. But my list consists of a few key extensions that are not frivilous and ones which I have installed on all of my systems.

In my original post, I had listed Adblock Plus, which is an extremely popular extension, and does indeed work well. I don’t personally use it, though. I do have it installed, but it is disabled. I found it would occasionally go overboard and some actual non-ad material would be removed from the page I was viewing. Internet ads, for the most part, aren’t as annoying as they used to be, and with high-speed Internet, I don’t often care. It would be handy for sites like MySpace which do annoy the crap out of you with ads.

Image Zoom was another extension I had on my list. I don’t really have this installed on any of my machines today. Once in a long while it can be a handy extension to have, but I almost never used it.

• Del.icio.us - The first extension that I install when I put Firefox on any system. I often tag pages in Delicious instead of saving directly to my bookmarks folder.
• Colorful Tabs - All of your page tabs are a different color! Brilliant, and easy on the eyes.
• Tabs Menu - Adds a Tabs menu to your program’s menu bar. Be sure to edit the preferences after you install. Turn on “Numeric Keyboard Shortcuts” and you can toggle through your open tabs with your keyboard. Very, very handy! This tab eliminates my need for Swift Tabs, another extension that creates tab-related keyboard shortcuts.
• Firefox Bookmark Synchronizer - This is the most handy extension you can put in your aresanal. It automatically synchronizes your bookmarks between different computers. If this makes you nervous, understand that it gives you complete control over the process. I just discovered this little gem and it is worth its weight in gold. This is a must-have!
• Bookmark Duplicate Detector - Prevents you from adding duplicates to your bookmarks.html file. It also can sniff out existing duplicates. If nothing else, this extension is worth installing, even if you only run it once to find the duplicates which you certainly do have.
• IE View Lite - Right-click any webpage to pull it up in Internet Explorer (Windows only). I am also aware of the IE Tabs extension that lets you view a page using IE embedded in a Firefox window, but I don’t use that add-on.
• Safari View - Opens the current page in Safari (Mac). Why would one want to do this? I don’t really know.
