The update of June 20 completely replaced the existing version, all files were lost.
Updating on June 20, the existing Thunderbird version in a flash of a second was replaced by a new blank one. All files and settings were lost. I needed an expert who (at cost of course!) managed to roll back the program with all files and settings as they were. This was a disaster, how can such effect happen? Right now I do not trust the updates anymore and will not implement new updates.

That would be rather unlikely. All your data such as messages, passwords and user preferences, and changes made while you use Thunderbird, are stored in a special folder called a profile. Your profile folder is stored in a separate place from the Thunderbird program, so that if something ever goes wrong with the Thunderbird program your information will still be there. It also means that you can uninstall Thunderbird and reinstall without losing your settings and data. The same goes for an update.
What can happen though is that Thunderbird creates a new profile (for whatever reason), and starts with that new, empty profile after an update. That would have the effect you described above.

Rolling back the application to an earlier version almost certainly wouldn't change a thing, and would likely cause other problems.
First navigate to the Troubleshooting information on the help menu. Scroll to the bottom of the "Application Basics" information and select the last entry. About:profiles. This will open a new tab showing the about profiles information.
This heading is followed by all the registered profiles Thunderbird currently has registered.
Do you have more than the current default profile listed? If so it is worth noting the name of the current default one.
Then click the "Launch profile" button for other non-default profile(s) shown. Clicking the button will launch Thunderbird in a new window with the selected profile loaded. If it happens to be what you are looking for, click the "Set as default profile" button and you're good to restart.

Good day, The expression "roll back" probably was incorrect to describe what the technician did do. He is not using Thunderbird himself so needed some time to get familiar with it. But from what I did understand he operated in accordance what your response suggested and got it all restored. Regards, Abraham Potappel.
