Sometimes, when Firefox doesn't quit cleanly (perhaps because it crashed, or because the whole computer crashed or didn't successfully terminated Firefox when shutting down), Firefox shows a Well, this is embarrassing page where you can manually select the tabs you want to restore.
I really like this feature, and I'd like to see that screen every time I start Firefox. I have a tendency of not closing tabs, and with this screen, I can choose which tabs I really want.
Is there a way (an extension I suppose) to get this message each time (other than manually crashing Firefox each time I want to quit it)?
