So, I tried Firefox - I just didn't exhale...B-)

Great browser, and it's *really* tough to make it the default browser inside Microsoft.  Not because the Men in Black Suits will come sweeping into your office if they see you spewing the Firefox user agent string, but because we use authentication *extenisvely* inside, and Firefox doesn't seem to play well in that environment.  If anyone's got any tips for resolving that, please let me know

I'll definately keep it installed on my machines (as well as Opera), and I will also be grabbing Security updates (patches) every time our Security team suggests one for installation.
