    I'm not going to rant about this at length, but I have never seen a tool that assesses fingerprintability of browsers which is not complete utter bullshit.

    Fingerprint randomization makes you easier to track because it is detectable and rare.

    None of these tools say what incremental identifying information an attribute provides given other attributes.

    For example, on a mobile device, your screen resolution gives a pretty good idea of what device it is because there are rarely more than a few popular devices at any given time with a particular screen resolution, and especially on a given carrier.

    If I know your IP address I can predict your time zone >95% of the time, and your language setting within a couple possibilities almost as often. If I know you're using Chrome/Firefox/Safari, you're almost certainly using a release less than two months old.

    TLS fingerprinting has approximately zero privacy impact.

    None of this is to say that I would be upset in the slightest if the advertising surveillance complex ceased to exist, but scaremongering kills credibility.
