Last night, at the second (!) Firefox 3 launch party in London, a representative from Guinness World Records presented Tristan Nitot with a certificate to say that the Mozilla project is the current holder of the world record for largest number of complete copies of a piece of software downloaded in 24 hours – 8,002,529. The UK contribution was over 300,000, just behind the Spanish but (sorry, Tristan) ahead of the French :-)
The certificate we were presented with actually says 8,002,530. However, on his way to the party, the Guinness representative remembered that he had absent-mindedly downloaded the software himself within the 24-hour period, and that his download was not permitted to count. Therefore, the official figure will actually be 8,002,529!
