well yeah, multiple tab management is my use case, what else? :P Your pain points are real, but incidentally not relevant to me. Since I've been using FF nightly fulltime for a while I restart the browser (with session restore of course) quite regularly, mostly every day. And I have the option enabled to confirm when closing multiple tab. Mostly because I sometimes hit Ctrl-Q by accident. Because conveniently, the "nuke everything" shortcut is situated right between the two most used shortcuts: Ctrl-W and Ctrl-Tab... :| So yeah, I happen to not be affected by this particular problem :P
