Firefox probably supported profiles before Chrome even existed. It always saved my life back in the days when you reinstalled the OS and you could just backup/copy over the entire directory of the profile.
Personally I edit the Firefox shortcut to add -p at the end of the target to get the profile manager showing up every time I launch.
I also use this when I spend a few weeks on a different machine at work: create a new profile, synchronize it with my account, then when I leave I nuke the entire profile.
