so much potensial.. not a replacement for bookmark all, restart, yet? Rated 3 out of 5 stars
this would be useful if it would scoop up tabs after firefox starts sucking up ram
or maybe after a user opens more than X subordinate tabs of a top level tab it scoops up alll other tabs
so much potential... until actualized I'll continue using default "bookmark all tabs", restartting firefox, and opening only those of my *current* focus.
