Will Firefox surpass IE in 2013?

According to foreign media reports, Asa Dotzler, a developer of Firefox, recently pointed out in his blog that in the past six years, the Web browser market has been changing. Every two years, Microsoft's Internet Explorer (IE) browser market share drops by 10 percentage points, while Mozilla's Firefox browser rises by 10 percentage points at the same time. If this trend continues, Firefox will surpass IE by 2013.
