Want to witness a Guinness World Record or, even better, to be part of it? People at SpreadFirefox.com can give you this opportunity, as they have announced the Firefox Download Day 2008.

Now you can take place in a world record by helping out your favorite browser to set the record for most software downloads in 24 hours.

All you will need to do will be to actually click a button and download Firefox 3 within the 24 of the Download Day 2008, which has yet to be decided.

Right now, on the official site, you can have a look at how many people have pledged to participate and, if you are a blogger or own a website, get one of the affiliate buttons and spread the word.
