ZDnet用了7页的报告比较了世界上最流行的4个浏览器：IE，Firefox，Opera，Safari。它使用了iBench和SunSpider作性能基准测试软件，测试平台为Windows Vista SP1和Mac OS X 10.5.2 Leopard，结果丝毫不出人意料：
虽然其中有一些还是beta测试版本，浏览器性能排名如下：Firefox和Safari走在Opera和Internet Explorer各个版本前面。将在6月发布的Firefox 3，性能超越，内存占用很低。没有其它浏览器在打开多个网站时内存使用比Firefox 3 Beta 5更少，只有极小部分网站在浏览器下显示出错。Safari和Opera，有着相同程度的兼容性问题。
