Rated 5 out of 5 stars

Best Session Manager for any browser. I arranged my Firefox usage completely around this plugin. For each type of work I load the appropriate session and if something changes the session will automatically update. I have *hundreds* of sessions saved, each dedicated to one particular area of study, work project or just general area of interest. I switched back to FF56 and I will stay with that version until there is a Session Manager for a later FF version or for another browser.

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