Over here, Firefox 2 passed all the test flawlessly, while Internet Explorer 7 failed 2 or 3 of them, and then crashed(And they said IE7 is good. <___<). I've never tried Opera, and last time I tried out Safari for PC, it couldn't even render GOOGLE properly, so I'm not touching that thing again. Anyway, Firefox has a lot of security addons for n00bs and risky surfers, so it wins against the rest anyway, IMO.
