I updated Thunderbird from 91.13.1 to 102.6.1. All Addons are disabled/uninstalled. iMAP account and SMTP. Normal Mode: I can send and receive if I do not check "save password". If I do try and save pwd it takes a long time but finally does refresh iMAP folders. No pwds are listed in the pwd manager. If I try and send and save the pwd it waits a long time and fails to send (connection failure) If I try and send and enter pwd without saving it it works fine. Troubleshooting (TS) mode: Works perfectly I enter the password for iMAP and for sending SMTP it sends and receives quickly and I can see the pwd listed in pwd manager. Restarting TB in normal mode after Troubleshooting mode and pwd manager list is empty. I tried copying logins.json after it had saved pwd in TS mode and replacing it after normal mode no luck. I tried with firewall on/off and antivirus on/off Thanks for reading
