Firefox runs on Mac OS; Internet Explore 8 doesn't (not natively, anyway, there's always Boot Camp).
that is a comparison.
So you want to compare a native application with a virtualized application on terms of Performance, NICE
Chrome is native on all platforms, why do you think it took it years to finally release on Linux & Max while it was already released 5 versions on Windows
sorry a typo I meant "Mac"
