Firefox 3.0 wins memory battle - uses less system memory

Mozilla's Firefox 3.0 browser uses memory much more efficiently than its rivals, according to an independent tester who wrote a memory-monitoring utility to track usage by Firefox, Internet Explorer (IE), Flock, Opera and Safari.

The poorest marks went to Apple's Safari 3 .1 for Windows -- Allen tested only the Windows versions of each browser -- which consistently consumed more memory the longer it was used. "Safari on Windows shows extremely poor memory management," he said. Other browsers, including Microsoft's IE 8 Beta 1, Flock's Flock 2.0, and Opera Software's Opera 9.5, were in the middle, memory management-wise, he argued.
