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?

Canvas rendering differs slightly depending on a lot of factors like operating system, browser, installed fonts, and many others. This information can be used to uniquely identify and track your machine across the web, even if you have stuff like cookies blocked and switch IPs. Just outright blocking canvas access attempts to prevent this. Keep in mind that while it can help prevent against canvas tracking, it can also be used as yet another variable to uniquely identify your browser, 'has canvas blocking enabled', just like blocking cookies, do not track requests, etc...
