Those crazy grassroots marketing folks over at the Mozilla Foundation have come up with another great initiative to help make Firefox the world's most popular browser. They plan to host a worldwide Download Day (click on the image for more info) following the upcoming official release of Firefox 3 (currently in beta). The total number of unique installer downloads will be submitted to the Guinness World Records organization for evaluation and potential inclusion in the Guinness World Records.

For the real keeners like myself, you can show your support (and get a reminder by email) by signing the pledge at the Spread Firefox web site.
