What is the privacy/security concern with canvas in web browsers? (self.asklemmy)

I have installed librawolf and I see that canvas access is disabled by default in all webpages so I started activating them when they bother me (whatsapp, youtube, element.io etc.). But then I figure that it is disabled for a reason. What should I pay attention to?

There are a number of websites that can tell you if your browser's fingerprint is unique and thus if you are trackable. Truth is, it always is because of the sheer number of variables involved, unless you're willing to disable a lot more than canvas, which breaks a lot more websites. Even Tor is more private despite having so many of their nodes ran by governments.
