Web Developer (toolbar)
Save as Image (I like it better than Screengrab)
Well you probably already knew the first two, but checkout Save as Image if you don't already have it. Also shortlisted is ColorZilla but I've not installed it. I'd like one that was just a colour dropper and less confusing UI wise. Attention Chris Pederick, how about putting a colour dropper into Web Developer?
I forgot IE Tab.
