And there's also the issue of a "fullscreendenied" being followed by a "fullscreenchange", which is weird, but I guess we could live with it if it was the only issue.

Of course.  I was really only talking about explicit user deferral actions; there might not be a good way to solve the problem of "ignoring the notification".  If it's anything like the current Firefox Geolocation notification, wouldn't a click in the non-popup area dismiss the notification?

Okay.  Assuming Firefox adopts the "Suggested UA Policy" portion of the API, equivalent full-screen window requests would be implicitly denied, so you would hopefully not be spammed by full-screen request notifications quite as frequently.
