According to Mozilla 125.000.000 people are using the foundations browser (Firefox).
John Lilly, chief operating officer i Mozilla, writes in a blog post that there’s now 125 million Firefox users. This is almost double the amount compared to when Firefox 2 was released last autumn.
The numbers are based on Mozillas Application Update Service (AUS). If Firefox is open and you are connected to the Internet it will check for updates daily. This way Mozilla can also track the number of installed and running browsers. The latest release was out last Friday by the way (2.0.0.11).
However, the number of users are not absolute it’s merely a prognosis. Lilly writes that number of “pings” received by AUS has been multiplied by 3. This is supposed to be a standard way of measuring unique users, at least in USA, and implies 3 persons sharing the same PC on average per week. Lilly himself thinks the FF user number are a conservative estimate.
