Mozilla's open-source Firefox browser is more and more popular in Europe, hitting nearly 29 percent market share in March. It's also growing in popularity in New Zealand and Australia, where it reached 31.2 percent, according to web analytics company Xiti.
In North America, however, March saw Firefox drop 1 percent. No one seems to know why.
I suspect it's just a momentary blip, however,over the past few years. There was a time that its growth might have been driven by ideology. Not any more.
No, Firefox increases in popularity now for one very simple reason: It's a better browser. The fact that it can increase at Internet Explorer's expense, despite IE coming pre-installed on 99 percent of computers sold, says something about Microsoft's increasingly tenuous hold on the desktop computer market.
