Mozilla aims for more than just a good Firefox 3.0, it aims for a Guinness World Record, all of course with the users’ help. With the motto “Set a Guinness World Record, Enjoy a Better Web,” Mozilla started a campaign with one clear mission: to become the most downloaded software in 24 hours.

As it appears, the classic competition between browsers turned into something fun. All users have to do is start downloading Mozilla Firefox 3.0 during the Download Day (which is still a mystery for now, but at least users will get the feeling they’re part of something great).

So far, Firefox seems to be gaining more adepts every month, and even though Internet Explorer is still ahead, there’s no doubt about it that Firefox is willing to catch up as quickly as possible. And while they do that, making their 3.0 debut fun is probably what every campaign lacks.

With Firefox 3.0 in its testing phase, an probably a couple of months before the launch, its developers are asking users to “spread the word” and set a Guinness World Record, an opportunity that many will probably miss.

What you should know is that for the time being, there isn’t actually a record for the most downloaded software in 24 hours, so why not set one now? If you want to pledge, and tell others to do the same, you can visit this website and join thousands of users who’ve already pledged to give a helping hand.
