I suspect there is something off with the browser fingerprinting logic which assigns high relevance to 'unique' characteristics like screen size while the reason for their 'uniqueness' is that the data is randomised on every request. Instead of assigning 20 bits to that single device with that odd screen size of 666x2045 (a different number on every visit) add a few bits to the variable 'randomises_screen_size' and ignore the screen size.

I was wondering about the fingerprintability of devices too. It seems a too easy thing to spoof. What if every visit was “unique” in terms of RAM or Screensize? Seems an easy metric to game.

The Librewolf browser (and I suppose most Mozilla based browsers could as well) does something like this - https://wiki.mozilla.org/Security/Fingerprinting.

Disable JavaScript and you're largely fixed. Amazingly enough there is a large enough contingent doing that such that you are far from unique (and it helps most all of the fingerprinting requires JavaScript)
