How can I find my address book's file to restore it from backup?

Recently, I needed to do a major upgrade to Fedora 43 so I did a full backup first for safety. After the upgrade, I needed to install Thunderbird to recover access to my email. For the first time in over 20 years, I had to re-enter the data for my various email accounts and now I find that my address book is gone. How can I locate the proper files in my backup and restore them while Thunderbird isn't running?

You would need to copye abook.sqlite and history.sqlite from the backup profile folder to the new profile. To find the current folder, try

- TB menu > Help > Troubleshooting Information

- click 'Profiles' near the bottom > about:profiles > Local Directory > click 'Open Folder' button

That should give you an idea where the backup folder is.

In my case I'll hve to restore those files from a compressed backup first. It's late now, so I'll do it tomorrow and report back.
