Review for Session Manager by Firefox user c7e57b
Rated 5 out of 5 stars
5 stars (THE most useful add-on I've ever found!) until a couple of days ago when Firefox suddenly didn't support it anymore.
I really hope you're able to convince the entire Mozilla development community that it's an absolutely vital thing for *everyone* who has more than one tab/window group that they have to work in as the day goes on.
