I’m running Windows 10 on a desktop. Thunderbird upgraded my program to 115.3.1 (32-bit) When it runs now it shows all of my old folders and the address book entries are there and incoming email notifications briefly pop up, but when I click on the popup, nothing happens. But all of the folders are empty. I experience the same thing on another PC. Any suggestions? I’ve seen this question on this forum before, but I have not see a suggested solution that works for me. Thanks for y’all’s consideration.
