You need the value as well, so better:

  for (let [domain, included] of filter.domains)

Done.

         {
           let urlFilter = "||" + domain + "^$document";
-          if (domain && filter.domains[domain] &&
+          if (domain && filter.domains.has(domain) &&

That's pointless, you already know that domain exists in filter.domains. This is
actually checking the value stored for the domain, meaning:

  if (domain && included && ...)

Whoops, Done.

               urlFilters.indexOf(urlFilter) == -1)
             urlFilters.push(urlFilter);

     notification.urlFilters = urlFilters;
     Notification.addNotification(notification);
     Notification.addQuestionListener(notification.id, notificationListener);
