Thunderbird-Hilfeforum

I just got a new computer. I've imported my address books, but autocomplete does not function, and a search of the address book returns nothing. It's as if Thunderbird thinks the address book is empty. I've tried importing in different file types, with no difference. Everything was imported to Personal Address Book, and that is selected in Settings. I'm using Ver 102.1.0. I have no add-ons. I've tried in Safe Mode, and it still doesn't work.

I was forced to download the newest version of Thunderbird and m adress list is obvriously not taken over. So I lost all my addresses. How ist this possible as you stated, all personal installations were taken over?
