The point to my original comment is fingerprint of extensions isn’t straightforward or free, ie requires intentionally designing a fingerprinting technique tailored to identify its behaviour.
CreepJS can really only detect Chrome extensions and very few Firefox ones. On Firefox, it can detect NoScript but not uBlock for example. This isn’t to say that uBlock can’t be fingerprinted, just that it hasn’t yet in CreepJS. Some extension don’t touch the DOM at all or produce any fingerprintable behaviour to the web page, so there for can’t be detected. Some don’t produce weird behaviour until a user interacts with some element in the extension or webpage.
Yes you are right. I don’t think there is a realistic way for most people to be anonymous or private online anymore given all these offensive and invasive techniques being used regularly now. Hell cloudflare fingerprints people with TLS alone, and that doesn’t care about javascript or anything else above it.
