Same here. Running FF 1.0 since the release. No pops, fast, everything runs smooth, looks good. Wouldn't consider going back to the nightmare of IE.
I use my super IE 6 in Drudge every day.
Its been running as smoothly as old brandy. :)
No problems whatsoever.
Wouldn't even dream of putting the dreaded open source, commie garbage firefox, on my machine.
