And as you can tell from the screenshot above, not only Firefox 4 but also the recently released Opera 11 browser has a steady lead over IE9 at this point.
Worth noting: Internet Explorer 9 isn’t compatible with Windows XP, ageing operating system that was released ten years ago but still has an enormous user base around the world.
When all versions of each browser are taken into account, IE still leads the global market with 45 percent, followed by Firefox with 30 percent and Chrome with 17 percent, StatCounter says.

In the US, IE (all versions combined) leads the market with an even bigger margin: 48 percent, followed by Firefox at 26 percent and Chrome at 14 percent.
