+==========================
+
+Reject use of ``XPCOMUtils.generateQI`` and JS-implemented QueryInterface
+methods in favor of ``ChromeUtils``.
+
+Examples of incorrect code for this rule:
+-----------------------------------------
+
+.. code-block:: js
+
+    X.prototype.QueryInterface = XPCOMUtils.generateQI(["nsIMeh"]);
+    X.prototype = { QueryInterface: XPCOMUtils.generateQI(["nsIMeh"]) };
+    X.prototype = { QueryInterface: function QueryInterface(iid) {
+      if (
+        iid.equals(Ci.nsISupports) ||
+        iid.equals(Ci.nsIMeh) ||
+        iid.equals(nsIFlug) ||
+        iid.equals(Ci.amIFoo)
+      ) {
+        return this;
+      }
+      throw Components.Exception("", Cr.NS_ERROR_NO_INTERFACE);
+    } };
