Mozilla is aiming to set a Guinness World Record on Firefox 3 download day for the most software downloaded in 24 hours.
If you are Firefox user and love the browser you can support the cause by downloading Firefox 3 on download day. The date is not yet fixed but it will be some time in June. Meanwhile you can take a pledge at Spreadfirefox site that you will get FF3 on download day. Other cool ways to support is telling your friends, colleagues and throwing a party.
