Just installed Mac Sierra on a new partition on my 2012 mac mini. Downloaded new Firefox an hour ago, but now, want all my bookmarks and other profile from Firefox 48.0.2 on my Mac 10.8.5 (Mountain Lion) partition, and can't find a way to do that. Have located my old profile folder (ofm0mf0f.default), but Sierra does not seem to put profiles in a similar place. New Firefox I just downloaded offers to bring in an older profile, but only from a physically different computer, not the same one with a different partition. Any suggestions? (I'm currently back using Mountain Lion and Firefox 48.0.2)

Thanks, gm
