If you’re one of the 8,000,000+ people who downloaded Firefox last month, you can be proud of yourself for helping to set a world record. If you need to show off your now totally-cool status, as part of a Guinness World Record, you can get your very own, printable certificate of appreciation from the Mozilla Foundation, who manage Firefox. I’m sure it’ll make a nice addition to your trophy and key-to-the-city collection, out in the garage.
