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.
