Firefox By Numbers

* We think there are at least 125,000,000 Firefox users in the world right now, give or take. That represents a doubling since Firefox 2 was released a little over a year ago, and significant growth in every country.
* At Mozilla we view market share as an important quantitative metric that can help us ask smarter questions and build better products, but it’s only one of many
* We have systems here that tell us approximate number of daily users, and use that information to inform much of what we do.

The rest of this interesting post from John Lilly, COO of Mozilla, explains the reasoning behind that number, and also offers some insight into what the Mozilla team are thinking these days. (Via Asa Dotzler.)
