Oh and I don't tend to see FF hang all that often after it's launched, although it does happen. I think it happens as often with Safari. But Safari launches way faster and does not hang on launch. Firefox hangs for up to 1/2 a minute with beachball on launch regularly, not recovering from a crash to load tabs (fresh launch), and then recovers and works normally. I wonder if it's doing housecleaning and it's just not that efficient at it or something.
