I’m posting on here because there is no response on the Thunderbird forum, however the fact that Thunderbird is now a Flatpak is relevant.
I’ve just installed Fedora-36 on a clean disk and copied the data from my old disk. When I have done this in the past Thunderbird used to find my profile and therefore the emails. Now it doesn’t, and copying the .thunderbird directory or the .default profile to /home/chris/.thunderbird doesn’t work either.
I tried Copying the .thunderbird directory from old computer onto new computer no longer works. | Thunderbird Support Forum | Mozilla Support, but “On your destination computer Locate the “Profile Folder” entry, then click Open Directory.” doesn’t do anything.
Now Thunderbird won’t even start, I just get “Your Thunderbird profile cannot be loaded. It may be missing or inaccessible.”
I suspect that the last time I did this successfully Thunderbird was an RPM package and it has since changed to a Flatpak, which probably means that data files are located somewhere different. I need to delete the lot, install Thunderbird again, then copy the data files to the Flatpak location. With a deb package you can use “purge”, is there a Flatpak equivalent? If not which directories should I delete and where should I copy the profile file afterwards?
