CloseReview for Session Manager by Firefox user 7b1518
Rated 5 out of 5 stars
I have been using Session Manager for years but only now with FF57 breaking everything I realize how utterly dependent on it I've become. To me, this is the most essential add-on of them all! I sincerely hope that Mozilla fixes their API asap and that Session Manager will be supported again.
This review is for a previous version of the add-on (0.8.1.13).To create your own collections, you must have a Mozilla Add-ons account.
