+reject-importGlobalProperties
+=============================
+
+Rejects calls to ``Cu.importGlobalProperties`` or
+``XPCOMUtils.defineLazyGlobalGetters``.
+
+In system modules all the required properties should already be available. In
+non-module code or non-system modules, webidl defined interfaces should already
+be available and hence do not need importing.
+
+Options
+-------
+
+* "everything": Disallows using the import/getters completely.
+* "allownonwebidl": Disallows using the import functions for webidl symbols. Allows
+  other symbols.
+
+everything
+----------
+
+Incorrect code for this option:
+
+.. code-block:: js
+
+    Cu.importGlobalProperties(['TextEncoder']);
+    XPCOMUtils.defineLazyGlobalGetters(this, ['TextEncoder']);
+
+allownonwebidl
+--------------
+
+Incorrect code for this option:
+
+.. code-block:: js
+
+    // AnimationEffect is a webidl property.
+    Cu.importGlobalProperties(['AnimationEffect']);
+    XPCOMUtils.defineLazyGlobalGetters(this, ['AnimationEffect']);
+
+Correct code for this option:
+
+.. code-block:: js
+
+    // TextEncoder is not defined by webidl.
+    Cu.importGlobalProperties(['TextEncoder']);
+    XPCOMUtils.defineLazyGlobalGetters(this, ['TextEncoder']);
