This is as days pass by, by Stuart Langridge

Since everyone’s loving the Firefox counter and it was written in response to a request to do cool things with the counter data from FF themselves, we present the Firefox countdown to fifty million downloads. Very similar approach to the counter; this just works out how long there is to go and counts down for you. (It’s also got a bit of Ajax in there to make sure it doesn’t go too far off track, plus, well, you gotta have some Ajax or you’re uncool, I think :))

At time of posting there is eight-and-a-half hours until it hits fifty million. Wow.
