Comment 0 for bug 1895898

Happened on upgrade from 78.2.1 to 78.2.2 lost all folder views .. Groovy .. regular updates via proposed..etc. (xubuntu flavour)

Installed thunderbird 78.2.2 from thunderbird.net into personal home directory works properly..

 so it is an ubuntu regression issue .. something has gone missing from the UI that puts folders on the screen (LH column)

.. view toggles do nothing in the ubuntu version ..

  Also F8 split view (RHS) also is not functioning
