The Mozilla Firefox browser is 5 years old! Now that Internet Explorer isn’t nearly as awful as it once was, and Google Chrome has started to raise some eyebrows, we often forget the effect Firefox had on the world.

They made a cool site, and a cool video.

And, of course, they published it on Twitter and Facebook.

Admittedly, I use Chrome most often these days. But Firefox is still an amazing product, and perhaps one of the best examples in the world of how a great open source community can contribute to a better world – literally.
