Do we have to reach a specific number of downloads in order to set the record?
This is the first record attempt of its kind so there is no set number. We'd really like to outdo the number of Firefox 2 downloads on its launch day, which was 1.6 million. Let's shoot for 5 million--the sky is the limit!
In other words, Mozilla is a lock to create a record as long as it sticks to the Guinness rules.
Mozilla is also hoping folks will hold Firefox parties. It appears that these parties will be BYOBrowser.
