Replying to [ticket:16760 cypherpunks]:
> You can determine a user's window size with CSS only. See
https://arthuredelstein.github.io/tordemos/media-query-fingerprint.html
for a live demo. I just tested in Tor Browser and it can still show me my
window size with security slider on high and all scripts disabled.
Works for me. The test shows a window size rounded to multiples of 200 or
100 as it should. My guess is that you resized your window and then did
the test. This case is not handled yet. See: #14429 for work-in-progress
in this area.
