Hi @srirambv

Do you think that https://fingerprintjs.com/demo uses WebGL Fingerprinting as on #478 ? Can you try to test https://fingerprintjs.com/demo ?

Thank you.

Closing this issue. Thank you for filing it, but for the reasons explained in brave/brave-browser#20268 (comment) (starting at "Again, i think fingerprint.js is sneaking by on misleading marketing here, not actual capabilities:") this is not a practical fingerprinting attack, its a very disingenuous commercial service trying to sell faux commercial fingerprinting services in a way that looks good on a small page with limited traffic, but would not work in the wild (and which Brave would provide strong protections against in the wild).

This is a non issue. fingerprintjs is not really fingerprinting anything here. For more information you can read here:
