I was taking a quick look at the browser stats on my personal site for February:
MS Internet Explorer 31.4 %
Mozilla 19.5 %
Firefox 18.9 %
Google Chrome 10.9 %
Unknown 8.7 %
Safari 6.3 %
Opera 0.9 %
IPhone (PDA/Phone browser) 0.7 %
Android browser (PDA/Phone browser) 0.5 %
NetNewsWire (RSS Reader) 0.4 %
Others 1.4 %
The detailed breakdown tells me that the most popular MSIE is version 8, with 13.7%. Then MSIE6 with 11.3%, and MSIE7 with 6%. Virtually nobody’s using MSIE9, with 0.2%. Worryingly there are a handful of hits from other older MSIE versions, although they’re all at 0%: versions 5.5, 5.01, 5.0, 4.01, 3.02 and would you believe it 2.0 all get a mention.
In Firefox land the biggest is version 3.6.13, with 13.2%, followed by a few on version 4.0, and other variations of 3.
Most of the Chrome users are on the current version 9.
There were a small number of hits (all less than 0.1%) from such rare beasts as SeaMonkey, Blackberry, Nokia browser, and the various versions of Netscape — everything from version 0.91 (!) up to 8.1. A bunch of various RSS readers are also in there.
But the real mystery is the figure of 19.5% for Mozilla. What does it mean in this context? Is it a munged reading for more Firefox browsers, a generic compatibility claim from various unidentified browsers, or something else? The detailed breakdown doesn’t tell me anything.
