Tor browser has a patch for this (at https://gitweb.torproject.org/torbrowser.git/blob/maint-2.2:/src/current-patches/firefox/0010-Limit-device-and-system-specific-CSS-Media-Queries.patch ) - might be a bit too agressive for general usage, but IMHO it wouldn't be hard to extract blocking of Mozilla-specific features outside of Chrome from it...
