I do not fully understand the purpose of this and why it is included as a Experiment. This is from Oct. and all I could find. https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices

Not sure if this applies and you would have to test : Type or paste about:studies in the address bar and press Enter to load that page.

If you are enrolled in a user interface experiment, it should be listed on this page and there should be a way to uninstall/remove or to opt out.

More info about SHIELD studies and how to opt out globally if you prefer: About SHIELD Studies. https://support.mozilla.org/en-US/kb/shield

hats all I can figure out if want more help with that post back.

Please let us know if this solved your issue or if need further assistance.
