Best Firefox Extensions Ever Created

I have been using Mozilla Firefox since 0.8 Version, now it is in 2.0.0.3

The best part of firefox is that it blocks all the pop up ads as well as you can even add some of the extensions what you like.

I personally like the following extensions.

1)Adblock Plus:

Great one if you want to block all kinds of ads on most of the websites.

2)Bug me not:

I use this to bypass any kind of registration with what so ever website.

3)IE Tab:

The beauty of this extension is that many websites are designed to properly work with Internet Explorer but when you open these websites with Firefox you will not be able to see them properly. Hence you install this extension to see those websites in firefox.

Mostly i use this option to read local language news papers which mostly work with perfect with IE not with any other browsers.
