Session Manager by Michael Kraft was a 3rd party add-on, not from Mozilla. It's a shame that extension stopped working, but its not up to Mozilla to fix 3rd party extensions.

https://addons.mozilla.org/en-US/firefox/addon/session-manager/

As stated there, Unfortunately do (sic) to limitations in the the provided APIs in Firefox 57, Session Manager cannot be implemented as a WebExtension add-on and will not work in Firefox 57 or higher. My only recommendation is to either not update to Firefox 57, use the Firefox ESR build or use a forked version of Firefox that does not remove support for add-ons such as CyberFox or Waterfox.

I'm not sure if enough of the missing API's that Session Manager needs to "do its thing" have been added since Firefox 57 was released, but chances are that is a dead add-on and probably won't be back.

Lack of API's is documented here back in late Dec 2017. http://forums.mozillazine.org/viewtopic.php?p=14785195#p14785195
