A programmer friend told me this which worked!

hit F12. This should bring a window/panel.
Said panel should have a Console tab, click it.

In the console tab, copy/paste the following and hit enter:

jq=document.createElement('script');jq.src='https://code.jquery.com/jquery-3.2.1.slim.min.js';document.getElementsByTagName(' head')[0].appendChild(jq);

that will load the jquery library so we can add a button to the form. Give it a few seconds to load, then copy/paste this into the console and hit enter

$($('frame:eq(2)')[0].contentDocument).find('#optionsform').prepend('<b utton>yeah');

That should add a button above the form which you can use to save
