Quoting Xiti – “Download Day” is plain to see: the average share of visits by Firefox 3 in European countries practically doubled between June 17 and 18, 2008:

* From June 9 to 17, Firefox 3’s market share is pretty stable…
* before rising from 3.6% on June 17 to 6.5% on June 18, 2008 with the launch of its official release.

Firefox 3’s share of visits then rises day by day to hit 9.3% on June 22, 2008, or almost one visit in every ten on average in Europe and a threefold rise during the week when “Download day” took place”.

They go on to show the table above with EU’s average market share hovering around 34% – which would be a 5% increase since the last Xiti report was published in April (http://www.xitimonitor.com/en-us/browsers-barometer/firefox-march-2008/index-1-2-3-127.html). The numbers in this table are pretty changeable, reaching 34% 2 days before the launch of Fx 3.

Xiti should be publishing their quarterly report at the end of this month – it will be interesting to see the numbers for EU over this longer period.
