Hello.
Have updated to "last" dev commit (Latest commit 21e2409 20 hours ago) and bookmarklet gives a loading page and loads nothing.

URL : javascript:(function(){var%20url%20=%20location.href;var%20otherWindow=window.open('about:blank','_blank');otherWindow.opener=null;otherWindow.location='https://www.xxx:80/frss/p/i/?c=feed&a=add&url_rss='+encodeURIComponent(url);})();

Works if I remove the :80 in the URL.
