Session is not restored
So before I was using neat extension session restore, which worked like a charm and restored my session even if Fx crashed terribly. Obviously after "delightful" migration to web-extensions Session Restore extension no longer works, but what's more awful - build in session restore doesn't work as well! Most of the time it restores previous browsing session, but then it fails one and a dozen of tabs is gone.
This is a huge no-no! No to the extend that I've switched to Vivaldi as my main browser (after a decade using Fx).
Any sensible solution to have working and *solid* session restore?
