vr mirroring does not work anymore in firefox 79

[massimo-bortolamei-hegias]

Have you noticed that since Firefox 79 rolled out, the mirroring of VR into the browser does not work anymore?
In hubs I get black screen, in simple AFrame examples (like this one https://aframe.io/aframe/examples/boilerplate/hello-world/) I get white screen. What's going on?

Hi @massimo-bortolamei-hegias. If you're running into this with other WebVR apps, you might want to file a bug report against Firefox itself.
I'd suggest also testing with the simplest WebVR sample to confirm it's an issue with WebVR and not Hubs specifically: https://webvr.info/samples/04-simple-mirroring.html

Hi @massimo-bortolamei-hegias I'm going to mark this as the answer for now, but if you find you can open this https://webvr.info/samples/04-simple-mirroring.html but can't use Hubs, please let us know so we can continue troubleshooting

Hi guys, thank you for your answer and sorry for the delay. I see the problem with the webvr example you linked as well.
I'll go ahead and file a bug report against Firefox.
