I am using Thunderbird 45.8.0 and Lightning 4.7.8.
I Downloaded this program Anyway.
And then, I saved this .xpi file on a proper location.
And then, I installed this Addon From file on Extension setting(Extensions window has setting button upper right).
It works very well without any problems.^^

Thank you. Philipp Kewisch.
