Rated 5 out of 5 stars

More than useful for me. I have successfully saved and restored all the windows and tabs even when the Firefox browser failed to restore the previous session accordingly. So, it will be very desired to have support on Firefox Quantum for this add-on. Anyway, once I have made the Firefox update I have lost the saved sessions and this is a not so pleasant aspect encountered on Firefox update.

This review is for a previous version of the add-on (0.8.1.13).
