    That is a bit confusing, but the feature called “Fingerprint Protection” (i.e. blocking known fingerprinters) isn’t the only protection built in. I’m not motivated enough to find a full list right now, but it also includes e.g. limiting the information in the User Agent header. I did at least find a list of things that were worked on at some point by searching for “Tor uplift”, which is a good starting point if you’d like to find more: https://wiki.mozilla.org/Security/Fingerprinting

    I’d also add that actually blocking requests to known fingerprinters does help. It’s more like camera’s getting disabled when you’re around: sure, from the point of view of the camera, it’s suspicious that it stopped working, but it can’t see you, so it doesn’t know who is standing out.
