That's the slogan for the Firefox 3 team's attempt to make a new world record for the most number of downloads a software achieves in a single 24-hour period. The date has not yet been fixed, is expected to be within a month's time.

They've already received close to a million pledges. If you'd like to join the effort, just head over to the Firefox Download Day page and sign up. You'll be sent a mail reminding you to download Firefox 3 on the big day.

Firefox users who've upgraded to the latest version (Firefox 3 Release Candidate 1) will find that their old version the Greasemonkey Extension no longer works. The older version of Greasemonkey was compatible only up to Firefox 3 beta.

The solution is to download the beta version of the latest version of Greasemonkey (version 0.8) available here. This works fine with the RC1 version of Firefox.

In other extension news, the Better GMail2 has been updated and is available for download.
