Download Day 2008 is a planned attempt to set a Guinness World Record for the most software downloads in a single day. As per the FAQ, they'll need over 1.6 million downloads, but want to shoot for 5 million. Which is nice, but sorry Firefox, that'll be no record. Flash Player blows that number away daily, not the 1.6 number, I mean the 5 million number. There have been over a billion downloads of Flash Player this year alone (less than 5 months), which averages out to over 6 million a day. And we've actually publicly stated that we've had days where downloads exceeded 10 million in a day. Don't get me wrong, I love Firefox, use it almost exclusively, and will definitely be downloading Firefox 3. But a Guinness World Record? Sorry, that's quite unlikely.
