Screen size leaking fingerprinting information
As visible in here
TBB is leaking information about me via screen size. Screen size is leaked only with JS enabled; however, it uniquely fingerprints me. (When I resize the window the screen size info is changed.)
It essentially defeats the purpose of using Tor, since it fingerprints me uniquely.
I am not sure what to do with it, since it probably is needed for JavaScript to work. One thing that would be possible is to force only certain window sizes for everybody across operating systems.
