Comment (by mcs):

 Replying to [ticket:14098 cypherpunks]:
 > I understand TBB does something to reduce the fingerprintability of the
 browser window size, but apparently it isn't enough as
 https://panopticlick.eff.org/ says they've never seen my screen size
 before. I'm using the latest TBB on the latest debian stable with the dwm
 window manager.
 > Could TBB please round the size to a larger interval so that I look like
 a more typical user? Thanks.

 For screen size, Tor Browser reports your window size.  Unless you resized
 the browser window, the size should be a multiple of 100.  What size was
 reported by https://panopticlick.eff.org/ ?

 Also see #13650.
