I'm currently building/testing a website with Firefox and Selenium, which requires interacting with the camera/microphone. To avoid having real hardware present, I've configured media.naviagator.streams.fake=true, however for some time now, this isn't enough anymore (not exactly sure for how long). When running normally (i.e. not headless), I can see that the permission prompt ("Allow website to use your camera/microphone?"), but I can't interact with it from Selenium. Is there a way to disable this prompt programmatically?
