According to new data from StatCounter, Mozilla's Firefox version 3.5 has successfully trounced Microsoft's Internet Explorer 7 in the global browser market. As of last week, Firefox 3.5 claimed 21.93% of the market, edging past IE7's 21.2% share. That said, Internet Explorer 6, 7, and 8 still collectively hold over 55% of the pie.
Meanwhile, Firefox 2.0 and 3.0 make up 1.01% and 9.01% of browser usage, Safari and Opera represent 3.03% and 0.42%. "Other" browsers account for 9.19% of the market -- much of which is presumably Google Chrome.
If you're wondering why these shares look pretty different from previously reported figures, it's because we usually cite Net Applications' research. StatCounter's accuracy is certainly open for interpretation, but it's still interesting to compare data between firms.
