This just in from Janco Associates: Firefox has lost 4% market share since January. You can find an excerpt from the white paper here or pay $249 for the full report here. Janco has claimed that this is global market share but I have my doubts because Firefox market share in Europe and on most of the rest fo the planet appears to be continuing to increase.

Indeed, XiTi Monitor reported at the end of April that Firefox was on the closing in on the 30% mark. ars technica has an excellent analysis of the XiTi research here. In related news it seems that IE users are dumber than folk who choose to use a Mozilla browser like Firefox. I wonder if that’s an indication of who going to be the next US president?
