LGTM

I would move it to the top of the file though, right after "use strict", but
your call.

+  window.chrome = window.browser;
+
 chrome.runtime.sendMessage({
   type: "app.get",
   what: "application"
 },
 application =>
 {
   // Load the mobile version of the options page on Firefox for Android.
   iframe.src = iframe.getAttribute("data-src-" + application) ||
                iframe.getAttribute("data-src");
 });
