Comment (by XhFpUeif0uIOCaq8HDlpZWBZMQXkjOSi):

 I'm using a pretty uncommon* window size (due to unique placement of my
 Tor and Firefox windows), so wouldn't it be very easy for an attacker to
 correlate my Tor-traffic with my non-Tor-traffic (coming through browsers
 with the exact same window sizes)?
 I'm not an expert but this seems to be a pretty major issue!

 Shouldn't you (at least) warn all Tor-users not to use Tor without having
 NoScript activated?

 * = unique according to panopticlick
