Profile Problem Developer Edition 68.0b1

Hi, since one of the last Updates i have massive Problems with Profiles.
I use roaming Profile under Windows with 2 Computers. But now each Time i use the second Computer it makes a new Profile, which is next Day also active at the first Computer. This is a NO GO! There are still Users, that do not want to sync online Profiles and this do not help for me because the second Computer still create each Time a new Profile. Please fix this.

This forum is mostly about DevTools, profiles are out of our comfort zone. If you file a bug via https://bugzilla.mozilla.org/enter_bug.cgi I can route it to the right person to take a look.
