On pure webmaster traffic I'm seeing about a 7-8% penetration with Firefox alone - and just recently. Lots of other alternatives in the mix now as well - and Netscape is about 1%. Also - MSIE has dropped to about 81-82% with the same traffic.
I just *finally* started using Firefox this week (posted on another board) and I really prefer it to MSIE. I tried others in the past and they just plain sucked. Glad I gave alt browsers another try... I think there are definitely some new winners out there that will make most give up MSIE in a heartbeat. Much faster, smaller size... so far so good.
