Thunderbird won't connect to POP/SMTP after Beta Update...
The May 30th 2020 update to the Thunderbird Beta version (77.something) caused the loss of connectivity to a POP server, and subsequent failure with the SMTP server on my laptop connected to RCN (my ISP). Now this particular installation of the BETA Thunderbird is several years old, and now it’s broken, and essentially useless. I need help getting access to the email file folders and porting them to another computer with a reliable public (non-BETA) release version of Thunderbird. Can someone please advise? Directions for doing this only work for Version 68.
Chosen solution
Never solved the connection issue to POP/SMTP. But I did find the place where the mail folders were stored and was able to restore full data access on the new computer. Turns out that two years ago - when installing Thunderbird on the laptop, I specified a folder on the C Drive for the email files - to make it easier to find them and back them up. I had forgotten that.
Am closing this.

To restate the issue: Thunderbird BETA had been successfully used for over a year on a laptop. Immediately after installing the lastest 77 Beta3 release (on 30-May), email stopped working - the connection to the POP/SMTP servers at RCN were "timing out". No amount of modifying the POP/SMTP settings (turning on StartTLS, or other settings, including changing ports) was able to bring this installation back. Due to the large amount of saved personal email, I've not been willing to experiment much. I can't find where V77 is storing the mail data files. There are directions here:
https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer
that show you how to "move to a new computer" - but that fails on the BETA.
Short immediate question: what is the same effective solution for the BETA version?
