The new behavior you describe will break notifications, since many pages
will want to bring themselves to the front when someone clicks on their
notification, and your patch prevents this. I suspect that the Firefox
behavior will need to change when they add support for notifications.

I still think that a superior change would be to prevent applications from
calling window.focus() or window.blur() in the context of a user gesture
once they've opened a new window. This would address popunders, while still
allowing notifications to work.
