I just took part in Firefox’s world record attempt, and you can too!
All you have to do is download Firefox 3 before 7.16pm (UK) or 8.16pm (CET) and you too could be a part of the “Most Software Downloads in a 24 Hour Period” World Record! :P
I got a certificate and everything!
You can also keep track of the current download volume as well as browse the official World Record site.
