Steps to reproduce:

I was testing the features in firefox 51 beta version 3 during testday 20161125. When I encountered Indicator to device permission test case 2 and loaded the URL in the instruction.

Actual results:

The web page loaded but the media content doesn't and it throws getUserMedia: NotFoundError.

Expected results:

The media content should have loaded instead of the error message

Due to this bug, during testing the device permission didn't show any notification and the i icon in the address bar doesn't change to respective icon. Like if it is video content the icon should change to camera but it doesn't.

When this happened, could you access the camera and microphone in other applications, like Chrome or Skype? 

Did your machine have both a camera and microphone installed?

It sounds like the application requests both audio and video but your machine doesn't have both available. Then this is expected behavior and it's up to the application to fall back to audio or video only. Chrome's behavior might differ but we are following the spec on this.

I don't have a camera and microphone installed on my machine, Andreas.

Working per spec - the webrtc.github examples don't handle spec-compliant gUM failure properly.  :-(
