Question

Do I need to assume, that a website with modern, advanced tracking techniques (e.g. Google) will be able to create a unique Canvas fingerprint by enabled JavaScript, therefore mitigating anonymity of Tor Browser?

Optional: How is amiunique.org able to do this despite having blocked "Extract Canvas Data" ?

Does Tor Browser get a unique fingerprint with JavaScript, even if HTML5 Canvas data is blocked (amiunique.org)?
