Similar to question #54

- if (gBrowserInit.delayedStartupFinished) window.LocationBar.delayedInit();
-     else {
-         let delayedListener = (subject, topic) => {
-             if (topic == "browser-delayed-startup-finished" && subject == window) {
-                 Services.obs.removeObserver(delayedListener, topic);
-                 window.LocationBar.delayedInit();
-             }
-         };
-         Services.obs.addObserver(delayedListener, "browser-delayed-startup-finished");
-     }
+ window.LocationBar.delayedInit();
