Mozilla has turned Firefox around. These numbers don't lie.
For the web browser, 2011 was an astonishing year. Google fundamentally changed our perception of what a web browser is and what it should do. According to StatCounter, Chrome gained 42.5 percent market share or 11.59 points, while IE lost 19.0 percent or 7.35 points, and Firefox lost 21.4 percent or 5.4 points. (For the remainder of this article I will only consider data provided by StatCounter, as it is the most comprehensive browser market share data set that is freely accessible.) You can love or hate Chrome, but there is little denying that Google's Chrome strategy, a combination of rapid browser development, convenient software delivery through silent updates, backwards compatibility, quick security fixes, and high-profile advertising, is working quite well.
Use Firefox, Chrome or whatever, just get rid of Internet Explorer
