Real Cause of the Missing Folder Pane in Thunderbird for Linux and Its Working Fix and Solution

[Turritopsis Dohrnii Teo]

Dear Linux Users Worldwide,

The real cause of the missing folder pane/folder pane not showing up
in Thunderbird email clients for Linux operating systems is extensive
and widespread corruption of the *.msf mail summary files or mail
index files. If your *.msf mail summary files or mail index files are
badly corrupted, the traditional usual recommended and oft-quoted
solution of deleting the folderTree.json and session.json files in
your mail profile(s) and later rebuilding them will not work, for
sure. Even if you try this solution for 1 trillion times, it will
still not work. This is because the files which are actually corrupted
are NOT the folderTree.json and session.json files. The real files
which are corrupted are your .msf mail summary files!!!

I have been repeatedly and stubbornly trying the traditional usual
recommended and oft-quoted solution of deleting the folderTree.json
and session.json files and later rebuilding them, for a few years, but
it did not work out for me at all. Now, today, 15 November 2016
Tuesday, Singapore Time, I have actually solved the problem of the
missing folder pane/folder pane not showing up in Thunderbird email
clients for Linux, which has plagued me for a few years.

Please refer to the following link/URL for my solution to the problem:

Concisely, the solution towards fixing the problem is to:

1) Exit or close Thunderbird
2) Go to your email profile, e.g. /home/user/.thunderbird/<profile-name>
3) Rename the *.msf files to *.msf.bak
4) Start Thunderbird
5) Create a new folder, e.g. "Backup 15 Nov 2016"
6) Move all your email messages from the INBOX folder to "Backup 15 Nov 2016"
7) Check and ensure that all your email messages from INBOX are
actually in your new folder
8) Exit and restart Thunderbird again
9) You should be able to start receiving email messages into your
Inbox all over again

For a few years, Thunderbird for Linux had fixed me. Now, I have fixed
Thunderbird for Linux.

Thank you very much for reading.
