Extensions are a way to add new functionality to
Firefox to enhance the web browsing experience. The list below are the extensions that I think every Firefox browser should have.
IE ViewWhile many sites nowadays work fine in Firefox, there are the occasional sites that are "IE only". Instead of copying the url, opening a new Internet Explorer window and pasting the URL, this extension allows me to simply right click and select "View this page in IE". Simply, effective, productive.

Web Developer
Adds a menu and a toolbar with various web developer tools. Resize windows, show the DOM, modify css on the fly.. you name it. This toolbar is so useful that
Microsoft created it for IE recently.

AdBlockJust say no to ads. This extension is simply the best way to filter ads may they be banner images, flash, or some other annoying feature. The filter can accept wildcards and patterns so it's cool to be able to block entire types of ads. On top of that I use it to remove the huge header banner on some sites, ugly avatars on messageboards, and unnecessary flash usage..

AdBlock Filterset.G This extension is a companion to Adblock that contains a bunch of preset filters for blocking intrusive ads.
