how does spoofing make you more unique? If I change my browser resolution to a more common resolution that would make me less recognizable, for example.
You can lie to the website and say your resolution is 1024x768. But what happens when the JavaScript fingerprinting checks the actual width of the view port? Your view port is most likely larger than your stated screen size.
Sounds like a limitation of the spoofing technology, and shameless spying on the websites part. I'm not a tech expert but is there nothing that you can lie to the websites about and they can't check or verify it? For example the list of fonts?
That one in particular you potentially could, though it does raise the question of what would happen if you report you have a don’t you don’t, and the site tries to push content using that font.
I had an add-on at one point (or possibly a uBlock origin setting?) to block all remote fonts and just use a local one. Might work fine if it's integrated with something like that.
because when you spoof whatever is fingerprinting you sees that you're actually providing fake data, so now you enter the list of the "hidden" instead of blending in. this is the core philosophy of tor browser, and a known fact. if you read partially the article i linked it talks about this.
