+## Firefox hidden iframe bug
+
+[Firefox has an old bug](https://bugzilla.mozilla.org/show_bug.cgi?id=548397) that occurs within iframes that are hidden with `display: none`. To resolve this, you can use alternate CSS to hide the iframe off-screen, with out `display: none`.
+
+``` css
+.hide-iframe {
+  visibility: hidden;
+  position: absolute;
+  left: -999em;
+}
+```
