[Note]:
-

[Affected versions]:
- Firefox 59.0.2
- Firefox Beta 60.0b8
- Firefox Nightly 61.0a1 

[Affected platforms]:
- Ubuntu 14.04 x64
- macOS 10.12.6
- Windows 10 x64

[Steps to reproduce]:
1. Open Firefox
2. Go to www.appear.in and enter a room.
3. Allow appear.in to use your camera and mic. (You need to use an external webcam which has a mic and select that one for both camera and mic in the dropdown)
4. Unplug your camera after you are connected to a room.
5. Go to Cam/Mic 
6. Open the dropdown menu for either the camera or the microphone.

[Expected result]:
- The dropdown menus are populated with other cameras and microphones that can be used.

[Actual result]:
- The dropdown menu looks as if it contains entries but only blank fields are displayed.

[Regression range]:
- This issue goes back to before the Quantum "era" so it may not be a regression. Will investigate ASAP.

[Additional notes]:
- This issue is reproducible ONLY when BOTH the camera and microphone from the same device are selected in the "Allow" pop-up from the beginning of a video conference on appear.in

Hmmm I am not able to repro this one. I am on Linux. After unplug I open the Cam/Mic settings and I see the built-in camera and microphone. Are you sure the external device is not the only device in your system?

On Linux it may have been only 1 cam but we've also reproduced it on a MacBook and that surely had 2 cams (FaceTime Cam + Microsoft HD 3000 Lifecam). Also...the mic has to be from that external cam. So, when the "Allow" doorhanger pops-up you should select your USB webcam on both the video and sound.
