Note; Deleting the extensions.* files (e.g. extensions.json, extensions.sqlite, extensions.ini) and compatibility.ini in the Firefox profile folder did not help.

New Update; Webutation

As an experiment, I created a new, blank profile. I then tried
to install Webutation. It is listed in the Add-ons Manager, but
not in the Add-on Customize Manager. I restarted several
times. And even rebooted. Still no joy.

Found another add-on icon doing the MIA;

Please note: I also tried two other "restart" add-ons. The others work fine.

I have installed FanFictionDownloader today and it shows in my add-ons/extensions,
but I can't get it on a toolbar to use it

With many many thanks to https://support.mozilla.org/en-US/user/cor-el,
my Webutation add-on is now working. 

See; https://support.mozilla.org/en-US/questions/1065850#answer-737929

...The extension uses the quote() function to enclose a string in quotes....
...This feature is obsolete...

The quote() function is used in the content/Overlay.js file, and needs to be replaced:

Old: var s = document.createProcessingInstruction('xml-stylesheet', 'href=' + href.quote())
New: var s = document.createProcessingInstruction('xml-stylesheet', 'href="' + href+'"');

Editing this file make the signing invalid, so you need to remove the META-INF folder.
======================================================
It's possible making similar changes for the other missing add-ons could repair them as well.
