  fixup! Firefox preference overrides.
  
  BB 45072: Disable XSLT.
  
  XSLT eventually is going to be disabled in all major browsers.
  While Mozilla has not started the process yet, it makes sense for us to
  do it, since XSLT has been a source of security bugs and fingerprinting
  vectors in the past.
