+/**
+ * We cannot yet use proper JS modules within webextensions, as support for them
+ * is highly experimental and highly instable. So we end up just including all
+ * the JS files we need as separate background scripts, and since they all are
+ * executed within the same context, this works for our in-browser deployment.
+ *
+ * However, this code is tracked outside of mozilla-central, and we work on
+ * shipping this code in other products, like android-components as well.
+ * Because of that, we have automated tests running within that repository. To
+ * make our lives easier, we add `module.exports` statements to the JS source
+ * files, so we can easily import their contents into our NodeJS-based test
+ * suite.
+ *
+ * This works fine, but obviously, `module` is not defined when running
+ * in-browser. So let's use this empty object as a shim, so we don't run into
+ * runtime exceptions because of that.
