Useful Firefox Extensions

[DCIScouts]

Hey everybody, I was just wondering, if you use Firefox do you use extensions? And if so, what ones do you use? I personally have a Forecast Fox (weather tool), some Strong Bad e-mail ones (full screen, etc...), and an ESPN sports ticker someone else mentioned in another thread. Thought this would be useful for people to find some browser tools that they like...

Webdeveloper is a good one if you make web sites, it has all the things you would want in one package, i use it a lot and you can change window sizes (see what it would look like on pc's with lower resolutions, and has instant shortcuts to validate pages, and show errors up, you can get it at:
