I'm running about 50%. My stats sw for my blog specifically isn't the best at the moment. The server logs cover more than just my blog. Here's my blog at the moment:

Netscape v6.0 54.39%
Internet Explorer v6.0
AOL's Browser v9.0
Internet Explorer v5.0
Internet Explorer v5.5
Opera v7.54 0.66%

I've seen a steady increase in Gecko usage over the year at my site. More details are in my post Browser statistics and choices from a few weeks ago.

The trend continues. Here's what it looks like for December:

Firefox 46.5%
IE 31.9%
Safari 7.6%
Mozilla 6.8%
Opera 4.0%
Netscape 1.4%

I run a low-traffic non-tech-related site. A lot, but not all, of my traffic is college students and professors. Since mid-September, my stats look like this:

61% - IE6
11% - Firefox
7% - IE5 Windows
7% - IE5 Mac
6% - Netscape 7

The other 8% has trace amounts of Mozilla, Safari, Konqueror, IE5.5, AOL 9, and (shudder) IE4 and Netscape 4.

Firefox has been climbing steadily. Traffic usually picks up in January, so it will be interesting to see a change.
