Perhaps it is a glitch in the tracking software, but my logs show that 90% of the Firefox browsers that come to this site are version 1.x rather than 2.x. Is there a reason for this? I have been on 2.x for quite a while and have a beta running of 3.x.
If you are still on version 1, Firefox automatic updater will not take you to version 2 automatically. You need to do it yourself here.
(Of course, the logs show 0.2% of you still using Windows ME. God help you.)
