You do have resources to limit fingerprinting, including beating many techniques, but it’s involved and I don’t have any useful links for you right now. On the site I linked, they provide resources to help you – including showing you exactly how they fingerprinted you. The easiest-strongest change is disabling javascript (The noscript addon makes this toggle-able and configurable), but of course that breaks all websites.
Is there anything I can do to mask the fingerprint to a degree or am I fucked?
