Does your webcam work in the new Firefox 53?

In a recent update of Firefox 53, support for some webcams may have disappeared or there may have been some shifts in the WebRTC API. Now we understand. We noticed this on tests. If in Firefox 52 the video was correctly captured from all the webcams involved in testing, then in FF 53 some cameras fell out, namely the built-in cameras. It is worth noting that the bug only plays with the built-in cameras for 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 reproduced on three out of eight cameras, not reproduced in Chrome and Firefox 52.

On Windows 10, all cameras are displayed correctly. Only USB cameras were tested.

On a Mac with FF 53, everything works well with both the built-in camera and USB.

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

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