Hello, I exported all my Thunderbird data, including adressbooks in an export file called: Thunderbird_profile_backup...then I uninstalled Thunderbird, because changes needed to made in the incoming and ourgoing mail settings. I downloaded Thunderbird again and installed it, entered the new settings and all my emails came back in. But I still need to import my address book which I did not save in a csv. file. It is in Thunderbird_profile_backup... I sse files in there like this filename: abook.sqlite.... Do you know how I can import my addressbooks from Thunderbird_profile_backup.? with many thanks
