Hi all,

I have been fighting today with the issue of the allow camera / mic popup
disappearing if firefox 28 looses focus after a getUserMedia query.


This is how 'doorhangers' work; they close if focus is lost (or you 
click outside of them) and can be reopened.



No event is fired when this happens which makes it very tricky to react to
in the UI.


Yes; this is a common issue.  Right now there's no easy way to deal with 
it, as you've seen.



I have tried rigging up timers with focus / blur events to try and detect
if this scenario has happened, but can not find a reliable approach.

Has anyone overcome this issue, or Moz guys, is this in your pipeline to
fix? The camera / mic box really should persist if the user switches app
and back to the browser again.


Given this is part of a larger, generic functionality I think that might 
be tough.  Other options would be a failure with a different error (this 
*will* break a lot of apps though and cause UI issues, since they'd need 
to re-submit the requests), or some type of event telling you if it's 
hidden or open (your best shot).  Mostly this is a question for the 
Firefox UI/front-end team.

Yes, common.  We occasionally angry comments on 
https://bugzilla.mozilla.org/show_bug.cgi?id=947266

So far, we’ve resisted adding any sort of feedback when the door hanger is 
hidden.  Since this is a non-terminal state (the door hanger can be opened and 
consent actually granted or denied), there isn’t a good way to provide this 
feedback to applications.

Yes, this makes your application a little less aware.  But we don’t want to 
remove user control.  If it were possible for an application or site to open 
the door hanger at will, then users could be badgered into consent.  We don’t 
want that.  We also don’t want to reveal what is happening with browser chrome. 
 That’s our user’s business.
