Way to go!

Joy and jubilation everyone, Firefox hit the 500 million downloads today! The spreadfirefox community is celebrating with lots of interesting activities and featured projects, such as raising 500 million grains of rice on FreeRice. That, says Mozilla, is enough to feed 25,000 people for a day.

It's been a very prolific year for Firefox, version 3 is on its way (and finally it's a fast browser), also Firefox reached more than 150 million active users that represent roughly 17% of internet market share.
