Are you talking about CSS-based fingerprinting?

No, not this is some amateur work. State of the art techniques css fingerprinting can uniquely identify 1 device from billions.

Also this is nothing but getting dimension of screen and other browser attributes which are useless now. The current state of the art cannot be mitigated unless you put a 95% penalty on performance on the CSS engine AFAIK.

The old link you keep pasting does not support this or your other hyperbolic assertions. Stop dangling claims of secret superpowers or support them.

Have a read: https://www.ieee-security.org/TC/SP2019/papers/405.pdf

All the links you provided describe techniques that would only work on mobile devices with access to the sensors. On my desktop PC there's no GPS, no gyrometer, no webcam and no browser access to my microphone.

And no access to that on mobile without security dialogs. Dude originally claimed it worked via CSS. I guess he doesn't have secret superpowers.
