Looking at the browser stats for my main blog, Wonko's World, it seems that the newly released Firefox 3 is proving pretty popular - 124 visitors have used Firefox 3 so far despite the first release candidate being available for only a month.
By way of comparison, only 88 people have visited using Opera since I started using eXTReMe Tracking 6 weeks ago, 199 used AOHell 9 and 216 used Safari. I also had 4 visits from a Playstation 3. Which is nice.
I've downloaded Firefox 3 to give it a bit of a test drive and although it's noticeably faster than IE7 and Flock, I don't think I'll be switching from Flock. The good people at Flock have already release their first beta of Flock 2 which is built on Firefox 3.
My advice? If you're using Firefox 2 or below then upgrade. It's faster and the default interface is a bit more modern and cleaner looking. If you're using IE7 then consider swapping - it's even quicker compared to IE7 and if it's as reliable as Firefox 2 then it'll be infinitely more reliable than IE. If you're a blogging, social networking or media fiend then use Flock.
