Just a possibility: the logins.json file may be corrupted or read-only or otherwise interrupted by an anti-virus program. You could delete that file, plus key4.db and cert9.db (with thunderbird not running) and try again. Another option would be to click settings>privacy&security and click saved passwords and then show passwords and if there are any shown to delete the rows completely. Exit and restart to verify that your change took place and then try password again. To repeat, this is just a possible explanation.

Thanks David, I appreciate your response.

Prior to getting it, I began fussing around and completely solved the problem.

I completely deleted version 115 from my computer and sent it to "software hell"

I installed the older version 102. It works perfectly! No more password nagging and fully functional.

I discovered the problem, at least in my case, was the new version 115 Thunderbird software and not my configuration which was preventing me from getting my email problem-free.

I guess "newer isn't always better"

Thanks again for taking the time to answer.

Peace, Alan
