IT WORKS WITH THUNDERBIRD 60.* !!!!!!

Just download the AddOn, rename it from .xpi to .zip and open the zip-file
inside the archive is a file called "install.rdf", open it with any text-editor (wordpad, editor, etc.)
look for the line with
<em:maxVersion>53.*</em:maxVersion>
and change it to
<em:maxVersion>61.*</em:maxVersion>
save the file and repack the archive
At the end rename the archive back to the extension .xpi and install it manually with thunderbird
