There are loads of extensions available for firefox. This is a list of the firefox extensions that I find most useful.

This is my favourite extension. If you're doing web design and css work you'll notice a huge jump in productivity from installing this.

Aardvaark.
A tool for quickly viewing the structure of page elements.

ColorZilla
An eyedropper and color-picker.

FlashBlock
Blocks all flash content from loading.

Bookmarks Synchronizer
Use an ftp or WebDAV server to sync your bookmarks between several machines.

StumbleUpon
Recommends interesting web pages.

Firebug
