Comment (by gk):

 A user on the blog mentioned a bunch of resistfingerprinting related prefs
 we still set and which should be covered by that defense already (see:
 https://blog.torproject.org/comment/276556#comment-276556):
 {{{
 the following prefs should be left at their Firefox default values if
 privacy.resistFingerprinting is enabled:

 dom.maxHardwareConcurrency,dom.enable_resource_timing,dom.enable_performance,device.sensors.enabled,browser.zoom.siteSpecific,dom.gamepad.enabled,dom.netinfo.enabled,media.webspeech.synth.enabled,media.video_stats.enabled,dom.w3c_touch_events.enabled,media.ondevicechange.enabled,webgl
 .enable-debug-renderer-info.

 However, 000-tor-browser.js still changes them, except dom.netinfo.enabled
 (setting the obsolete dom.network.enabled pref instead),
 media.ondevicechange.enabled, and webgl.enable-debug-renderer-info.
 }}}
