I've had a few crashes while running FF 46.0.1 and restoring the tabs with Session Manager hasn't come up. Then I noticed that the add-on link in Tools(Menu toolbar option) disappeared. All the more after checking to Show my
windows and Tabs from last time in "When FF starts" it didn't work too. I'll be happy if the issue will be solved.

update: Solved in an hour
