Comment (by cypherpunks):

 It's not only way to get fingerprints today. Look at #9881
 Many desktops in the world shares 640x480 (that reveals by this bug for
 example), but not so much browsers shares limitations for avail window
 size (that reveals by #9881).

 > Proof of concept screen size fingerprinter
 Can it fingerprint automatically without click on page visit?
