Firefox 3 Download Day Download Day is now officially over. The final score is 8,252,518, 5 times the number of downloads on the previous release. Download Day is an event by Firefox set to create a new world record for most copies of a piece of software downloaded in the first 24 hours of its release. They've spent the entire month before this preparing for it, only defining a release date 3 days ago. Now the only step left is to have the attempt verified by GWR. The event is being recorded by Guinness World Records. More about the event here.
