Comment (by Marnes):

 This is indeed bad for the user in terms of fingerprinting.

 The following is the fingerprint of vanilla tor browser, freshly installed
 and unmodified: http://puu.sh/dN8co/58ddab89bb.png (1 in 2.5 million)

 This is the fingerprint of my regular Firefox with a bunch of add-ons and
 no particular privacy features: http://puu.sh/dN8bC/7c22d700bc.png (1 in
 800 thousand)

 The unusual resolution is unique to people with my screen resolution + tor
 browser < people with my screen resolution. It causes the fingerprint to
 be 4 times worse.

 The only specific measures I took in Firefox is settings
 plugins.enumerable_names to an empty string to prevent Java from sending a
 boatload of compatibility info, and using click-to-play for everything.
