 -  my accounts (not sure where they would be)
 -  my local folders (I see what looks like the folders I had)

If so, how? Thanks ...doug

Downgrading is not supported. That us because the data structures in the profile folder are changed by the update process and there is no backward compatibility.

You can use the -allow-downgrade command line option I discuss here https://thunderbirdtweaks.blogspot.com/2019/09/i-lost-my-profilemail-on-update-to.html but you are almost certain to see something not make the transition.

A better result will be obtained by reinstalling 115 and fixing whatever the issue is. Personally I do not like the user interface, but to all intents and purposes it does appear to be well received and stable.
