Firefox 4 Leapfrogs Internet Explorer 9 in Downloads, Usage

The world still loves Firefox. That's what we learned from the launch of Firefox 4, which in a single day managed to grab hold of nearly 2 percent of the worldwide Internet browser market, according to StatCounter's statistics. That's more than both Opera 11 and IE9, the latter of which was released last week and claims a 0.87 percent share of the market compared to Firefox's 1.95 percent.

"Firefox 4 has really hit the ground running and has eclipsed the launch of IE 9," commented Aodhan Cullen, CEO, StatCounter. "Although IE 9 has undoubtedly been hampered by its lack of compatibility with Windows XP."

Download numbers tell a similar story. Microsoft was justifiably excited when IE9 logged 2.35 million downloads in its first 24 hours, proof positive that if you build a browser that doesn't blow, people will at least try it out. However, people were more eager to try out Firefox 4, which logged more than 4 million downloads in its first 24 hours, and now sits at over 7.4 million downloads (and climbing). You can keep track of Firefox 4's download stats here.

Did you download IE9 or Firefox 4? What did you think? And if not, what browser are you using?
