(Sub-) Folder names are suddenly hex values, some settings and filters are gone

After waking my computer from sleep mode (which I do tens of times each day), and after starting Thunderbird, most of my subfolder names are now hex values (like "05befcb191"). Also, all tabs (except for the main tab) have closed and when I click "Get Messages", it tells me the certificate for the mail-server has not been seen before, and when I retrieve my email, I get error messages that it can't find my mail filters.

Obviously, something has become corrupt. It doesn't seem any of my mails have gone missing (fortunately).

How can I troubleshoot/fix this?

I do have a few months old backup, but I don't want to blindly restore since I will loose all mail since then.

Isisombululo esikhethiwe

I think I have found what caused the problem. Apparently something went wrong when Thunderbird updated itself. Let me try to explain.

When I copied over a known working backup of my profile folder, it still didn't display the proper folder names. That led me to conclude the problem wasn't in a corrupt file or anything, but more logically that something in Thunderbird changed.

I then went searching through the old profile's files, trying to find where it links the visible folder name with the actualy folder name. Turns out this was stored in a file called "panacea.dat". This file was not available in the new profile. When I copied this file over, it still didn't display the proper folder names.

So I then went searching through the new profile's files. I found it links true/visible folder names in the file "folderCache.json". Each folder has an entry with a parameter "foldername". I changed that to what it should display and that way I got my folder names back.

So I think what happened is that something went wrong when Thunderbird (after updating itself) tried to convert panacea.dat to folderCache.json.

I checked the profiles folder and noticed that the physical folders (and corresponding message/index files) also have those hex values as their names. I then checked my backup and on the backup the folders/files had the exact same hex values as names.

So somewhere in the profile there's a file that "translates" those hex values to true names - and this file apparently is now corrupt or missing.

I backed up my Profiles folder and copied the Profiles folder over from an older backup (when it was all still working). And still the folder names are hex values.

So the problem isn't in the Profiles folder. Possibly in the registry? Or does Thunderbird store information in other locations?

Sorry for making this a one man show, but when I try to rename a folder to it's original name (for instance, rename "04b83342c2" to "Bank Mails", I get an error message:

"A folder with that name already exists. Please enter another name.", even though there are no physical folders with that name.
