I'd prefer an if here, since there is only one case.

This code is essentially identical to Chrome and we will most definitely add
more cases here once we have more UI.

+  {
+    case "get-settings":
+      var host = extractHostFromURL(request.frameUrl);
+      var selectors = ElemHide.getSelectorsForDomain(host, false);
+      event.source.postMessage({reqtype: "get-settings-response", selectors: selectors});
+      break;
+  }
+}, false);
