Recommend Good Firefox extensions for developers? (I'll show you mine if you show me yours...)

Nobody has given a link for Web Developer, so there ya go! That thing is pretty damn awesome and does alot of things that multiple smaller extentions normally handle.

Another tastey one is Stealther. Handy if you want to ignore sessions and disable cache with a simple click. Also useful for hiding any "late night research" you happen to be doing.
