This feat has somehow stayed under the radar for me as I’ve just caught wind of this today. Apparently a few days ago (the night of July 30th), Firefox hit one billion downloads. While obviously this doesn’t constitute as one billion users actively using the program, the Digital Daily explains it best:
As Mozilla CEO John Lilly told me this morning, “It’s a billion votes–a billion intentional decisions–for people to take control of how they interact with the Web. We–the whole Mozilla community, really–are really proud to have been part of building a product that’s been downloaded so many times, but more importantly, we’re all proud to have helped people take more control over their online lives by making intentional decisions.”
