This isnt really an enhancement, but is everyone here aware of this new cross-browser fingerprinting method? ​Have there been any tests of the current Tor Browser's resistance to this?

If already discussed elsewhere, redirect to relevant ticket.

I tested the webpage on the Tor Browser on a computer running Windows10 and it got stuck on 'fingerprinting GPU' and the display of graphics - probably due to webGL disabled but i cant be sure.

In terms of defenses to this:

  • Disabling javascript is the obvious. webGL is already disabled by default in the Tor Browser, so all ok there ?
  • disabling the microphone is another measure. i cant see that Windows10 has the option to disable speakers aside from turning the volume down to 0 for all apps, or for just for the Tor Browser.
  • Is running the Tor Browser in a virtual machine kind of overkill to be completely sure of preventing this (and other) cross-browser fingerprinting?
