Firefox doesn’t have themselves to thank though, as the reason for being number one is mostly because of Internet Explorer losing market shares due to Google Chrome going from 5.05% in December 2009 to 14.58% in December 2010.
The European Union decided some 1-2 years ago that Windows users in Europe should be presented with a list of alternative browsers so everybody would have to decide whether or not they wanted to keep Internet Explorer as their primary browser or select from a few others, including Firefox and Google Chrome.
Opera and Apple’s Safari continues to have around five percent market share each.
Worldwide, however, Internet Explorer is still leading with 46.95% with Firefox in 2nd place with 30.76% and Google Chrome in 3rd with 14.85%.
The above data has been collected by StatCounter by gathering information from three million websites worldwide.
