I can't see any difference between mozilla 1.0 RC1 and RC2. Maybe it's mail or news changes. For browsing both are rock solid (although I've found most everything is rock solid on OSX,) fast, and thoughtfully designed (tabbed browsing, cookie support, and full javascript controls come immediately to mind.) Apparently RC2 should run on MacOS 8.5 and 8.6 although I've yet to confirm this. You can get RC2 here.
