Comment 36 for bug 1600622

My 2c, no website should ever be able to dictate if my monitor goes or not to standby. More to the point, I think the screen locking is also disabled and this makes it a potential security issue, as it would be trivial for any external party to weaken the security profile applied by the user. Just as we control how we must explicitly allow websites to grab audio, or video, we should also explicitly control if it can override other system settings. Or, there should be something similar with how macos or android grants some permissions on a per-app basis.
