Mozilla's Firefox 4's browser usage share grew over two and a half times in the six days since its March 22 launch, a web analytics company said today.
According to California-based Net Applications, Firefox 4 accounted for 3.7% of all browsers used Sunday, up from last Tuesday's 1.4%.
Firefox 4's Sunday share was double that of Microsoft's newest browser, Internet Explorer 9 (IE9), which was released March 14.
Overall Firefox have lost 2.5% of their users, and IE 4.8%, while Chrome have increased their users with 5.3% the last year. Apple Safari have increased with 1.9% in one year.
