Comment (by jsha):

 I can still reproduce in FF31.0 with master and with 3.5.3 at
 http://norilskonline.ru/v-mire/kosmos/681-neopoznannyy-obekt.html, but the
 sol.sapo.pt link is now broken. I cannot reproduce in Chrome.

 It's pretty mysterious. With the rule enabled, I don't see any additional
 errors. I do see HTTPS Everywhere rewriting the YouTube URL, but no
 subsequent fetche sin the Network panel for the rewritten URL.

 From comment3, I agree that something like
 https://trac.torproject.org/projects/tor/ticket/4408 (content
 introspection differences) might be involved.

 I also note that the problematic page uses
 http://norilskonline.ru/engine/editor/scripts/common/mediaelement
 /mediaelement-and-player.min.js, which might be trying to do something
 smart about loading various versions of the Youtube player.
