  // so avoiding using an array avoids serialization on the side passing the
  // filters.  Since an nsString can share its buffer when copied,
  // using that instead of InfallibleTArray<nsString> makes copying the filters
  // around in any given process a bit more efficient too, since copying a
  // single nsString is cheaper than copying InfallibleTArray member data and
  // each nsString that it contains.
