Review for Session Manager by Komsip
Rated 5 out of 5 stars
This is a great extention for everyone who read many times at once but still have to change subjects now and then and have a completely different set of tabs open, to later go back to what you were doing. I tried it out since I downloaded it and it really works exactly the way you'd want it to work. With plenty of room for personal customization to suit your specific needs. This is something I should have found years ago. This capablity should be in firefox by default.
This review is for a previous version of the add-on (0.6.2.3).To create your own collections, you must have a Mozilla Add-ons account.
