Great Extension, Highly Recommended for Power Users Rated 5 out of 5 stars
This great extension has solved for me an old and painful problem.
I tend to keep 100~300 tabs open in all my Firefox sessions. And I also like to keep my sessions open overnight. Now I have no problem restarting Firefox anytime to add/remove extensions or restore crashed sessions. I don't even have to worry about the memory consumption as idle tabs will be automatically unloaded.
Works well with Tree Style Tab and Multiple Tab Handler.
