Firefox profiles no longer separate
A while back I created two profiles in Firefox, to separate bookmarks needed for work and private life. Yesterday I unfortunately needed to reinstall macOS, and now, after reinstalling Firefox, the two profiles are no longer separate when I've logged into my Sync account. I can still see two profiles when I go to about:profiles, but opening one or the other does not make a difference. I hope someone knows how I can fix this, thanks in advance!
