Does your webcam work in new Firefox 53?

In a recent update of Firefox 53, support for some webcams may have disappeared or some changes occurred in the WebRTC API. Now we understand. We noticed this on tests. If in Firefox 52 videos were correctly captured from all webcams involved in testing, then in FF 53 some cameras fell out, namely the built-in cameras. It is worth noting that the bug is played only with built-in cameras under Windows 7 and Windows 8. It does not play with USB cameras on Windows 10 and does not play at all on Mac OS.

In the FF console, the bug looks like this:

MediaStreamError { name: "InternalError", message: "Starting video failed", constraint: "", stack: "" } 

Firefox 53, Windows 7 and Windows 8.1 64 bit

The test results show that the bug is played on three cameras out of eight, it is not played in Chrome and Firefox 52.

We are going to send a bug report to the Mozilla Firefox team and your help will help us gather more information on this issue.

If you have Windows, a webcam and Firefox 53, please write if it works on the test pages.
