Problem Solved: "Sorry, the F1 service is not available at the moment." Rated 5 out of 5 stars
But it stopped working after SSL certificate expired on plugin configuration page f1.mozillamessaging.com
I had to add certificate exception on this page - and now it works.
Please renew addon page SSL certificate.
