that's a great way to get even more fingerprinting potential, each additional switch is another bit of identification on top of the actual fingerprint itself.

Mozilla refuses to add _any_ toggle to disable RFP's control over features it touches, including even an about:config entry.

My "fix" for this involves using a janky old version of an addon that attempts to muck with the CSS/JS to reproduce the effect.
