I'm actually not finding *any* problem with the existing external content block handling the new YouTube iframes that have "//" in the URL. They seem to work fine, in HTTP and HTTPS sites, in Firefox and in Chrome (on Ubuntu). See for example: https://mahara.org/user/aaronw/nz-has-seals
I'm going to mark this issue "Invalid" for now. If someone can verify that the YouTube iframes with "//" URLs actually cause problems, feel free to reopen.
