Good old times… Unfortunately, as that website points out, it doesn’t really matter if it detects incorrect values: for fingerprinting it’s sufficient that the values be "consistent* through visits, even if wrong.
I’m not sure whether it needs JavaScript to read the values? I’d like to know.
If it reports the same values for everyone, or randomizes them every start (like display resolution and timezone), then it becomes less useful for fingerprinting. In fact, it calculated a different fingerprint altogether this time, though it did know it was the second time I visited.

Yeah no, it actually will need JS for most of that information. Otherwise the server will just get the HTTP request header which includes your browser’s user-agent and some other less identifying stuff, plus maybe your IP (unless you’re behind a VPN).

99% of the Internet doesn’t work without JS. Yes, having a script blocker that blocks google static & whatever else will help you some, but it’s not perfect & this type of script blocking specifically is under heavy attack right now.
Thanks for the useful info!
Indeed randomizers are good. But as you wrote, it’s sad that so many sites just don’t work, or work badly if one alters some of those values…
Maybe the long-distance future of sane people will be I2P or similar infrastructures…
Letterboxing could help here making consistency a bit more random by setting each websites height/width to different values. Mullvad-browser does this by default. I think on other FF forks you have to turn it on in about:config.
