Can I reverse an upgrade?

Upgraded my Thunderbird 10.2 to current version 32.0.1. All my filters, local folders, sent copies, and address files have disappeared. I did not realize that local information would be obliterated with an upgrade. Is it possible to back this out and restore to the files that appear to be in the Local AppData on my Windows Vista machine?

I will have to spend hours to days recreating these folders, filters and contact lists from the giant pile of emails that this "upgrade" has left me.

It is possible that Thunderbird has just lost track. Can you tell me if you have one or more profiles?

Make hidden files and folders visible:

Help > TRoubleshooting Information click on 'show folder' button

It will open on the currently used profile. click on the 'Profiles' part of directory - see image below. In my example it shows I have one xxxxxxxx.default profile folder and I'm open on that folder. How many profiles do you have?

Thunderbird did lose its way, and I did find more than one user profile. Since I normally don't leave email up if I'm not directly using it, I brought Thunderbird up and down a few l times as I found more file paths to try in the settings. Fortunately, on the third start, Thunderbird found its own way back to my regular user profile before I made a much worse mess.

Next time, I'll make a better back up and follow your helpful suggestions. Thanks
