XiTi Monitor, one of the premier web survey companies in Europe, has just released their November Browser Barometer report.
Of note, I.E. has dropped below 60% in Europe. It was in November that I.E. fell below 70% for the first time globally.
Also interesting is just how little change there's been in the European countries over the last 6 months. I'm not quite sure I believe that, given the fluctuations month to month, but it is what it is.
Finally, the rankings from Gemius, which covers Eastern Europe, are all positive for Firefox and nothing but negative for IE which has or is about to fall below 50% in most of Eastern Europe.
