Comment (by mikeperry):

 Yeah, I think the actual fingerprinting issue due to maximizing is better
 handled like #14429 attempted to do. This notification is just to inform
 the user that what they are doing is not a great idea and that they should
 avoid doing it.

 I think the notification box after the fact like we did for the slider is
 sufficient for now as a stopgap. I think the doorhanger is only needed if
 we were going to actually act on the notification in some way by setting
 some kind of site permission, but we're not.

 I'm thinking the notification box could say something like "Maximizing Tor
 Browser can allow websites to determine information about your monitor
 size, which can be used to track you. We recommend you leave Tor Browser
 windows in their original default size. [OK]"

 I'm also thinking until we get #14429 into better shape, this notification
 box should display every time.
