Microsoft's Browser Still Loses Ground to Firefox

Although Microsoft recently reported the 100 millionth installation of Internet Explorer 7, Web measurement firms said that the new browser is simply a replacement for older editions and hasn't had an impact on Firefox's continued rise.

According to Geoff Johnston, an analyst with the Web metrics company, Firefox's share of the U.S. browser market, has continued to grow for the last three months. "I thought that IE 7 might flatten Firefox's growth, but it's not taken a hit from IE 7. All the movement there has been internal, from IE 6 users upgrading," he says.
