I tried to use [this extension](https://github.com/plibither8/asciinema-player-for-github). On Firefox, I get this error:

Content Security Policy: The page’s settings blocked the loading of a resource at [https://asciinema.org/a/Hr6o4z5O2AMEZKnTTPQenpOot/iframe](https://asciinema.org/a/Hr6o4z5O2AMEZKnTTPQenpOot/iframe)? (“frame-src”).

I get that this isn’t really a problem with asciinema, but is there a way to work around it?
