I've used Firefox all my life because of Firebug. Then after a while it just got so slow that it was unusable and the experience became terrible. And then I switched to Chrome. I'm not fond of their developer tools as much. Not as good as Firebug. I guess I'll give FF another shot.

I switched for the same reasons but kept FF around mainly for Firebug. After using and getting use to Chrome Dev Tools, it is actually no different and in some cases better. I don't do as much front-end dev as I used to though... But I do remember reading that the FF team worked with developers of popular plugins like Firebug to help make those plugins run better, use less memory and cause less memory leaks. You may find those plugins a lot better now.
