This is one of two addons I cannot do without (the second is TabKit 2 for vertical tabs). I've tried various other addons that purport to do what these do, but they weren't near as good. I've tried updating Firefox, but without Session Manager and TabKit2, I have reverted back to an older version. Somehow session manager was gone for a while (I don't know how long, but i'd get an "unavailable" when i tried to install it), but this morning Firefox said an update was available! I immediately got rid of the half-dozen useless session addons and reinstalled session manager! Finally, back to normal. (Unfortunately, the only sessions it had available were from Feb and Mar (it's now Dec.) But, that's OK - I'll live with it... and make new ones...
