Firefox just reached  500,000,000 downloads. This is an absolutely phenomenal milestone for Firefox. It is sort of hard to imagine what that number means. For some perspective, that’s roughly the audience size of 10,000 Rome Colosseums combined. It would be the weight, in kilograms, of 8,500 Boeing 747 airplanes. In dollars, for $500 million you and 15 of your friends can fly to the International Space Station.

OR, you can affect change and invite 15 of your friends to play a game and feed 25,000 people. With your help we can break another milestone today with FreeRice.com –500,000,000 grains of donated rice in one day. Imagine helping to feed the hungry while picking up some new vocabulary too!
