My point is that parental blockers are nowhere near as strong as they should be if a basic feature of Firefox can easily render them all useless. Any tech-savvy 14 year old could easily figure this out, and the only other way to stop them for good is to never grant them Admin privileges on any of their computers, and to mess with the registry on Windows or the policies.json on Mac/Linux to disable certain browser settings. This is beyond the abilities of most normie parents.
