I've been using Thunderbird for several years, but I still don't quite understand how it works. A week ago or so I was unable to add attachments to email and it was suggested to me that I should reinstall Thunderbird, and the claim was made that I would lose neither my email nor the settings. So I did reinstall Thunderbird and found out that all my Local Folders were gone and that I had to configure all my email accounts from scratch, which I did.
Since I regularly back up my home directory using the Ubuntu Backups app, I thought I could restore my Thunderbird data from a recent back-up. Following some advice I'd found on the internet, I restored the ~/.thunderbird directory from a recent backup and saved it at the desktop. Then I replaced the current ~/.thunderbird directory with the one restored from the back-up (cp -r ~/Desktop/.thunderbird/ ~/). When I re-launched Thunderbird, I noticed the following: (1) All the Local Folders that I had created in 2024 and before were restored, but not the more recent ones (i.e, the ones created in 2025 and 2026). (2) The restored Local Folders did not contain any emails dated after early September 2024, which I think is the time when I upgraded Ubuntu 22.04 to Ubuntu 24.04. Looking at the restored profile directory (~/Desktop/.thunderbird/cvb2eouj.default-release/Mail/Local\ Folders), I see that the missing Local Folders are not there, which makes me believe that the problem happened at the stage of making a back-up of my home directory rather than during the restoration process. Is it possible that the location of Thunderbird data moved from ~/.thunderbird elsewhere at the time when the transition to the snap version of Thunderbird took place in Ubuntu 24.04? If so, what is the new location? Knowing the names of some of the missing Local Folders, I have tried to search for them in my home directory, but found none (find /home/<user name>/ -name <name of a missing Local Folder> -print).
I also wonder whether I could use backup data that were created at the time when I uninstalled whatever version of Thunderbird I had prior to clean installation of Thunderbird 157.0. I recall that uninstallation took a lot of time because a back-up was being created (sudo snap remove thunderbird). I have no idea where that back-up was saved, however.
So now I have Thunderbird 157.0 installed and configured on Ubuntu 26.04, I can send and receive e-mail in all my accounts, but Local Folders created after September 2024 are missing, and the ones that exist contain only relatively old emails (older than September 2024).
I would appreciate help and ideas on how to restore the missing Local Directories and emails from home directory backups.
