If i close thunderbird and reopen it that contact is gone from all address books. Reproducible: Always
does it also happen with thunderbird started in safe mode? https://support.mozillamessaging.com/en-US/kb/Safe+Mode can you determine that the CAB address book has changed on disk before you shut down thunderbird? iirc the name in the profile is history.mab http://support.mozillamessaging.com/en-US/kb/Profiles
When adding a new contact to the address book(S) you must put something in the "Screen Name" of the new contact else when you shut down Thunderbird and restart it that new contact will be gone.
