Great and useful Rated 4 out of 5 stars

This is an awesome extension, almost exactly what I was looking for. Is there really no way to save the tree structure using Firefox's built-in session saver? Ah well, no big deal I guess. I'd just like to have some extra options like amount of time for autohiding, etc. Thanks for the addon!
