website https://webqr.com stopped reading QR after Firefox updated to 58.0

more options

I used website https://webqr.com to read QR codes, but after Firefox updated to 58.0 (one hour ago) there is no image from the webcam in this website and so it is no longer reading QR codes. I'm using Windows 10. I reported to the website also but the problem started after Firefox update, this tells me that Mozilla changed something, the JS console says "navigator.mozGetUserMedia has been replaced by navigator.mediaDevices.getUserMedia", I downloaded the website to run it locally (I have done it before and it worked), I did the replacement but still no image from webcam and no QR reading :(

Webcam problems are Driver problem FF can't remove them. It could block them based on security measure and that means you need to look at your settings on this. What QR codes are you referring to?

QR codes like those in electronic product boxes. I've tried «about:config», «media.navigator.permission.disabled» (I was desperate), when "false" Firefox asks for permission but «https://webqr.com» shows no image from webcam so it can't read QR codes. This is weird because Firefox asking for permission tells me it is recognizing the camera, but there is no image. Remember : there was image before the update. In the mean time I will have to use Chrome (which I don't like) until a new Firefox update solves the problem. By the way, «https://webqr.com» still works in FireFox for Android, Firefox for Windows seems to be the problem.

Samo here. They've an error on the website.

if(moz)
   {
       v.mozSrcObject = stream;
       v.play();
   }

I think it should be v.SrcObject = stream; . Prefixed version is not going to work anymore due to https://bugzilla.mozilla.org/show_bug.cgi?id=1183495.
