I've been using Thunderbird for years with no issues but suddenly this week it froze and although I could send e-mails from my Mac (running on Sonoma 14.5) I couldn't receive any. There was no message error, just nothing happened: it was frozen. So I finally opted to disinstall and then reinstall Thunderbird and now have incoming messages again but everything else I had: all my tags, e-mails older than a day ago, my address book have all gone. I've tried doing "import from profile "default" then choosing to import accounts and settings, address books, and mail messages but just get a message that "import failed unexpectedly, more information may be available in the Error Console" but I've no clue how to find the Error Console in question. Can anyone walk me through how to fix this issue and recuperate my old Thunderbird account without using all sorts of technical terms? I'm not IT-fluent! Many thanks.
