There was a decent amount of hub-bub with the release of IE9 but I am, obviously, more curious about the legit release of Firefox 4. Supposedly there are all kinds of performance enhancements and, I can only hope, that means it has become less of a resource hog. For reasons unknown even to myself I've always been a fan of Firefox - it's extensibility can often be its downfall but from a developers standpoint it is the best browser to have around. From an everyday usage viewpoint, lets hope that this new release makes it a no brainer.
