Re: What browser do you use?
Definitely Firefox. In fact I remove all icons for IE as soon as I do an install. It saves your windows when you close, lets you use tabs, and blocks nearly every popup (although lately the ones on ISH are getting through for some reason).
And now that you can open an IE window in Firefox, there's no reason to ever need to use IE. (plugin)
My only disappointment is the Linux version doesn't seem to be as updated as the Windows version.
