When Firefox first added Tab Groups I was absolutely thrilled with the exponential increase in FF's ability to handle and organize large numbers of tabs. However, I was simultaneously baffled at how they neglected to add what I thought was an obvious need created by this new Tab Group system: the ability to handle and organize the Tab Groups themselves.

Before I discovered Session Manager, Tab Groups were merely a nice way of uncluttering a window with a large number of tabs during a browsing session. WITH Session Manager, Tab Groups are a powerful way of quickly accessing large amount of oft-used, topic-specific sites during any browsing session you happen to need it, while keeping them isolated from anything else you have open.

I do have ONE suggestion for Session Manager:
A one-click "Quick Save" option that would save each Tab Group in a separate session with the Tab Group Name as the Session Name, automatically overwriting any other session with the same name. Perhaps it could automatically add the Session Name as the Tab Group Name when it gets restored as well. That would make this extension essentially perfect IMO :)

This review is for a previous version of the add-on (0.8.1.1.1-signed).
