Session Manager is easily one of the most useful and, for me, essential Firefox Addons.
I could not imagine using FF without it anymore.
This Addons is the sole remaining reason for me to not switch to Firefox 57(+) yet, and I really hope Mozilla is coming through and will provide/support the remaining API calls necessary to go forward.

Thanks for this wonderful Addon and all those years of support!
