title: Thunderbird 68 won't import old account from ~/.thunderbird folder
body: <p>I reinstalled my system from ubuntu 20.04 do manjaro. 
  I saved ~/.thunderbird folder from the old system to an external drive. After, I copied the folder back to home and started Thunderbird it does not seem to see the profile. Although it can read some of the data, like the Address Book but no account settings, no folders, nothing else.</p>
  
  <p>I found the help page
  <a href="https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer" rel="nofollow noreferrer">https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer</a>
  and tried to do it but it doesn't help. Thunderbird found my old profile and it is visible in about:profiles and set as the default profile, so everything looks like thunderbird has read the profile settings but does not understand them</p>
