We need to work out what browser APIs exist to do this since this the display of the bar is something that happens indirectly as a result the theme installation and isn't something that's triggered from the page explicitly.

@aswan any thoughts?

This seems like something that the browser should be doing automatically (i.e., if there is a change to the theme's status coming from somewhere other than the bar, the bar should be dismissed). I'm not familiar with the existing code that displays that bar so I don't know how difficult that would be, but can you open a Firefox bug?

In future, it would be great to see themes show the same behavior than extension:
Show a door-hanger confirming install instead of the notification bar.
(Unifies UI for users, and we would not need to maintain 2 separate systems)

@designakt yep I agree, if we can stop the default behaviour then we can implement the notification / UiTour for themes too.
