In the recent update Firefox 53 has lost support of some web cams or there were some changes in WebRTC API (getUserMedia). We are investigating this now. We have noticed this on our tests. Firefox 52 was able to capture video properly from all testing devices, however in Firefox 53 some cams have stopped working. Though this bug (?) is reproduced on Windows 7 and Windows 8 with embedded cams only and not reproduced on Mac OS Sierra.
This is how the error looks in the FF console:
MediaStreamError { name: "InternalError", message: "Starting video failed", constraint: "", stack: "" }
Firefox 53, Windows 7 and Windows 8.1 64 bit
In the test results we see that the bug has reproduced on two cams of eight and not reproduced in Chrome 57 and Firefox 52 (previous release). The testing page:

We are going to send a bugreport to Mozilla Firefox team and your assistance would help to gather more information for the report.
If you have Windows, web cam, and Firefox 53, would you check if it works?
