This is interesting. According to SiteMeter, the excellent service I use to monitor my Web traffic, 31.8% of all visitors to this site are now using Firefox. That’s up from 24.76% last October. While the Firefox share grew 7%, the share for Internet Explorer 6.X dropped almost exactly the same amount, slipping from 64.88 to 57.37%.
Another curious stat jumped out of this chart, however: Internet Explorer 7.X has gone from 0 to 2.51% market share since Beta 1 was released just over a week ago. That’s much higher than I would have expected.
Of course, these numbers are for a site that is aimed at techies and bleeding-edge types. Out in the mainstream, the numbers are very different, I bet.

So there’s still people using IE4 and Netscape3? Wow. I’m using Maxthon 1.3.3 which translates as IE 6.x on your graph. I think I’m one of the few people left who aren’t that impressed by Firefox so far that I use it every day.
Ed, I wonder if SiteMeter detects Opera when it is masquerading as Internet Explorer, or other browsers … ? Keep us posted on these stats (perhaps quarterly or biannually?). I would be interested to see if Opera’s share rises with the release of Opera 8.02, which presents itself as “Opera” unless configured otherwise (the opposite of earlier versions, which masquerade by default).
Well if you go to this site www. astalavista. com
(one of the millions like it out there) with IE you WILL! get infected, but with firefox .. no problem
