Comment 68 for bug 483929

Yes, this bug shouldn't be at 62 comments. All of our new notification work is based on a single button for "yes", and the user ignoring and moving on for "eh" (where "eh" means probably no, but I can go back and say yes later if I feel like it). There are a lot of reasons why we think this is better, no forced choice, supports undo, etc. And I think all of those ideas apply here as well.

Single "Restore Session" button: restores the session

Closing the tab, opening a new tab, navigating this tab somewhere else, etc: starts a new session
