I've been using Opera for years, and I go back and forth between Dragonfly and Firebug. Firefox + Firebug is sooo sloooww. But, Dragonfly isn't quite as full featured. BTW, Opera 10.5 is really fast. The Beta RC is still crashing quite a bit, but I really like the new features that have been added.
