Fantastic, manages my sessions and tabs, the only add-on that allows me to work properly, as I should be able to.
The fact that FireFox has failed to keep this add-on workable is a great shame.
I began to use it when I had system issues which crashed the PC, this Session Manager helped autosave my sessions and has many other features - frankly it is the only add-on that does what it does.
I have relied on this add-on for years now and refuse to work without it.

I will only work with Firefox versions that are compatible with it.
