privacy.resistFingerprinting

Hello. In next firefox 50 release probably will be released the option to use some of the tor bundle patches in firefox through: privacy.resistFingerprinting

1. The first patch blocks enumeration of plugins and mimeTypes. Sites may retrieve the information from the browser, and use it in fingerprinting. With the patch in place, Firefox returns no information to the site blocking the requests effectively.
2. The second patch works in a similar manner. Firefox returns 0 for screen.orientation.angle and "landscape-primary" for screen.orientation.type when sites or applications request the information.

This maybe will replace the current configuration for window.screen and navigator.plugins + mimeTypes.

Generally the uplifting of the Tor Browser patches into Firefox is a very interesting thing in deed.
Thanks for pointing that out, for some reason I wasn't aware of it yet.

I'll have a more detailed look at it later, but at least the 2nd patch seems insufficient to me. The actual resolution tells you much more than just the screen orientation.
