Mac OS X Lion is a beauty to behold, and its benefits aren't just skin-deep. Firefox's problems in OS X mirror what it suffers in Windows, with the addition of memory problems found in OS X. Like Chrome, though, its Windows 7 build far out-paces the OS X version. This browser suffers the same issues on OS X as in Windows 7, with the added problems of lowered JavaScript and DOM performance, as well as slower page load times.įirefox 6 is pretty close behind Opera. Opera takes third place on OS X, and its cross-platform scores are really close, earning Opera the distinction of providing a steady experience across multiple platforms. A lack of HTML5 hardware acceleration, hoggish memory usage, and poor reliability hold back Google's browser here. Chrome takes second place on Lion, though its performance isn't even close to what we saw in Windows 7.
