MacOS Catalina - Tbird, latest update, was working fine for months up until this morning. I have my primary email account set up as well as a few gmail accounts. The gmail accounts got new mail but my primary did not. I switched to a new user account on the Mac and set up a tbird there using Imac. That works just fine, so I know my isp is working correctly. Long and short, I restored my profile back to last night 5pm but that didn't fix. I tried restoring back to a week ago, no go. Then I restored the entire ~/Library/Thunderbird folder, no go. Finally just created a new imac account which is reading emails now just fine but it's using up too much isp server space so I want to go back to the POP arrangement as before, using the previous profile. Are there other bits to restore to besides ~/Library/Thunderbird?
