> Petr, are you going to open a Firefox bug to fix their code or shall I do it?

Please file it. I haven't had time to read whole thread and I don't know what
shall be the right fix. For now I used just:

   template <typename... SpecialValueMappers>
   ErrorResult ExtractErrorResult(SpecialValueMappers... aSpecialValueMappers)

-#if (defined(__clang__) || (defined(__GNUC__) && __GNUC__ >= 8)) && \
+#if (defined(__clang__) || (defined(__GNUC__) && __GNUC__ >= 11)) && \
     !defined(XGILL_PLUGIN)
     return mVariant.match(
         [](ErrorResult& aException) { return std::move(aException); },

But if you are busy I can do my best to report it.
