In the week after the arrival of Firefox 5, Firefox 4′s market share dropped by more than half, going from 16% to 7.2% according to analytics company StatCounter. During the same period, Firefox 5′s share of the market rose form 0.50% to 10%, signifying that the new version took on the decline of Firefox 4 and more.
By comparison, Chrome’s most recent upgrade made Firefox’s gains seem less dramatic. With the release of Chrome 12, Chrome 11′s share plummeted from 17% to 2.7% in the first seven days, a drop of approximately 84% in usage. Chrome 12′s market share, on the other hand, jolted up from 0.70% to 15.5% in the same time frame.
Firefox 3.6 stayed flat during the same seven days that Firefox 5 rose and Firefox 4 fell, likely due to the latter’s opt out update offer, which Firefox 3.6 lacks, having effectively moved users to the next edition.
