Video not placable or viewable in firefox
When creating page video will not place in firefox or play in firefox. It will in safari.
So there was a recent Chrome/FF Security update that disallows http iframes in https pages (which the scroll kit editor uses).
I've fixed the Youtube lego, so that adding a youtube url will default to https, but if you are embedding an iframe through the iframe lego, just make sure to use https instead of http.
