10 Favorite Firefox Extensions
As of March 2006 my favorite Firefox extensions include:
1- Adblock - Everyone loves this extension!
2- Filterset.G Updater - The ultimate companion for adblock.
3- PDF Download - When I click on a PDF, I don't really mean to open it in my browser!
4- Tab Mix Plus - A good session saver and Tab feature enhancement
5- Image Zoom - The name says it all
6- Customize Google - Adds more features and privacy to Google search output
7- Window Resizer - If you have big screens, you will miss seeing webpages in 1024x768
8- Copy Plain Text - If you hate seeing HTML styles while pasting from webpages to your docs
9- Chrome Cleaner - Cleans up theme/extension dumps from your browser and makes it faster
10- IE Tab - IE is evil. But sometimes you need it. Remember WindowsUpdate!

How about Fasterfox? It's like the Internet, only faster :P
How about "Web Developer", "Greasemonkey" and "Right Encoding"?
Those are all great extentions of course. I do not use WebDeveloper because I am not doing Web Development! and FasterFox, because I do all the tweaks manually thanks to about:config.
Don't forget to check the site with the extension contest winners at
