How to Hide Firefox Camera Icon Overlay in Windows

Question

I'm working on a kiosk project that uses Firefox and mozGetUserMedia to access an attached camera.

The problem is, even using kiosk addons (like mKiosk) this icon appears at the top of the screen whenever the camera is accessed using mozGetUserMedia:

Here you can see it at the top of the screen.

I have tried searching through the options on the

about:config

page, but I can't find any setting that disables this. It only shows up on Windows, and not OS X.

How can I disable this icon?

Answer 1

In the about:config settings, set privacy.webrtc.legacyGlobalIndicator to false.
