The Mozilla Foundation, creators of the amazing Firefox browser, are attempting to set a Guinness World Record for the most software downloaded in 24 hours. “Download Day 2008,” as they're calling it, is slated to coincide with the release of Firefox 3. Here's hoping their servers can survive the onslaught!
If you haven't tried Firefox yet, the release of Firefox 3 is a good time to give it a spin. I highly recommend it.
Update: I should note, in case it wasn't clear, that Firefox 3 is not out yet. It's supposed to be released in June. Also, it seems the Mozilla Foundation is pretty much guaranteed to get the record, since according to the Guinness World Record site, no such record exists yet.
