Unfortunately, it's not just JS, but several other indicators. In practice, if you don't use the Tor Browser, it's as if you decided to leave tracks everywhere, almost identifying yourself. Yet, this is not common knowledge among web users. These are the things that children need to be taught in schools. The society as a whole needs to be aware and learn how to protect itself.

That is victim blaming, just because you do not know that everybody out there is tracking you does not mean that you have decided to let them.

I agree that this is something people should be more aware of and school is a good place to start. However it is up to browser manufacturers to fix this, not users.

The comment says "it's as if" you are intentionally leaving traces everywhere. So, the effect is the same as doing it intentionally, not that users are to blame somehow.

Wonder if the Facebook Containers for Firefox can stop this type of fingerprinting too.

True, but I'd wager that if Facebook is using mouse movements to track users, it means those other methods aren't foolproof.

Absolutely.
