Hi Michael, really great Add-on !!!
It´s the one I´m using most on FF. I was shocked when after the automatic upgrade to FF57 (forgot to disable on one device) the session manager didn´t work any more.
Would be great if you could post on your page whether you plan to upgrade the Add-on to FF57 or not and until when, then I can decide to wait.
