This is the most important Firefox add-on to me. When the other session managers sucked for FF57, I felt like being homeless. I had to downgrade to FF56.

I also wonder why did FF update crippled this kind of add-on. If they had to do that, they should have made it built-in.

Excellent job, Michael.
