Earlier today at Google I/O, the company announced that its web browser, Chrome, was now 70 million users strong. That’s a big number, and up more than 100% in the past year. But wait a second, let’s get some perspective. Enter, Mozilla’s Asa Dotzler.

As he points out on his blog this evening, while Chrome may be at 70 million active users, Firefox is at nearly 370 million active users. And while Chrome grew by 40 million users in the past year, Firefox gained over 100 million new users in the same span — yes, more users than Chrome has total. He also made a nice chart to underscore his point.
