Well maybe not the world but at lest a World Record. The Firefox team is trying to set a new Guinness World Record for the most software downloaded in a 24 hour period. The launch day has not yet been set but most likely will be some time in June. The total number of pledges is near 400k right now and growing. So head over to their website and pledge to help. People who have pledged will get email updates when the release is near. So not only will you get to help set a World Record but you will get one of the best web browser out there today. And, it free so why not give it a try.
