Re: [w3c/permissions] A new permission for canvas data (#165)

>The browser can handle that, as mentioned in the Firefox bug up above, by whitelisting a set of local fonts visible to the webpage. That avoids the fingerprinting vector entirely, and I'd support that. (The page would then only have access to the whitelist fonts, and whatever they pull in themselves via @font-face.)


According to my previous (long ago) experiments even identical fonts and browser binaries leak some info about environment. I had posted the link above, you can try that yourself on your PC. First install TBB into a main system and acquire a fingerprint. Then fully restart TBB and acquire another fingerprint and make sure that they match. Then run an OS in a VM, install TBB there and aquire another fingerprint. Then compare the fingerprints. You may also want to try it with different versions of usual Firefox with privacy.resistFingerprinting=1.
