Firefox 4 thumps IE9 in first day download contest

That number was nearly triple the 2.4 million copies of Internet Explorer 9 that Microsoft claimed were downloaded in its browser's first day of availability last week.

It should come as a shock that Firefox 4 has trumped IE9 in the first day download contest: Firefox 4 has a built-in edge because it runs on Windows XP, the 10-year-old operating system that IE9 doesn't support.

Web metrics firm Net Applications said last month that XP accounts for more than 61% of all copies of Windows used on machines that went online in February.

During that same 12-month period, IE has lost 4.8 percentage points, during Google's Chrome gained 5.3 points and Apple's Safari grew by 1.9 points.

Users can download Firefox 4 for Windows, Mac OS X and Linux from Mozilla's site. People already running Firefox 3.5 or 3.6 can grab the upgrade by selecting "Check for updates" from the browser's Help menu.
