I'm no IE fan - you've flamed me before, but in the interest of accuracy, I'll point out a Firefox download doesn't equate to a Firefox adoption. To update to the latest point release, you have to do a new download. You can't just do an update. So if you want to update from 1.0 to the current verision, you do a download and get counted again. Or at least it was that way when I last updated to 1.0.3.
They have fixed that, you now get upgrades not whole new programs..
