I know this is not typical, but I just run into breaking bugs on Firefox on every platform which prevent me from using Firefox (except Intel MacOS, which I have not used, and Windows, which I haven't used in a few years.) For Safari, the problem for most platforms is that it doesn't run on most platforms. It doesn't really count to me if I can't use it on my computers. (Caveat that there are non-Safari webkit browsers, but they're not very good.)
