Prior to reformatting the disk and reinstalling Ubuntu, the backup was a
straight copy to a USB mass storage device.

Like the backup, the "restore" was a straight copy into the
.mozilla-thunderbird MAIL folder.

Previously T-Bird saw the files and adopted them - not this version.
This version is quite different - new features - new menu items etc.
and I'm suspecting, new mail file structures.
