All browsers should just copy Firefox. Granted I haven’t tried IE8— but I don’t know why IE continues to suck version after version. How is that possible? Don’t they have like billions of dollars to spend on R&D? Maybe they should make a FIX CRAPPYNESS department.
I read an article of FF sometime ago, and most of the features are done by volunteers, which is amazing considering how much $$$ Google and MS threw into theirs.
