Well, it has now become official, Firefox 3 has set the record for the most software downloads in a 24 hour time period and have been added to the Guinness World Records. The time period coincided with the launch of Firefox 3 and ran from 18:16 UTC on June 17, 2008 to 18:16 UTC on June 18, 2008 during which a total of 8,002,530 people downloaded the software.
The downloads also did not stop there, as of current, which is just about two weeks since the launch, Firefox 3 has been downloaded just over 28 million times. Overall that is pretty impressive, but at least according to this user, so is Firefox. If you have not already I would suggest giving Firefox 3 a try.
