I switched to Firefox about a year ago on Mac, and coming from Chrome I've been totally satisfied. Not that I've run any comparison benchmarks or anything, but it'll load basically anything I want to throw at it, has the right set of extensions to keep me rolling, and the only real performance issue I've noticed with sites is the occasional rendering block waiting on content I have blocked with uMatrix. But that last one's my fault, not Firefox's.
