I use CardBook as a replacement for the built-in contacts and for keeping contacts in sync with my nextcloud instance. Everything was good until thunderbird got an update: I can not see my contacts anymore nor can I edit or delete address books.
Do you have any clue what could be wrong?
System: openSUSE Tumbleweed, KDE desktop
I’ve had the same problem yesterday by switching from Th45 to Th52 and back : to recover, stop Thunderbird, then you have to delete in your profile in storage/permament/chrome/ the file .metadata-v2 (if this is not sufficient also delete in storage/permament/chrome/idb the file and directory *Ckaoro*)
