HTTPS-Everywhere Firefox add-on breaks BBC news videos
When HTTPS-Everywhere (v3.5.1) is enabled in Firefox (v28.0 running on 64-bit Windows 7), embedded BBC news videos fail to play. The video component either shows a static image, is completely black, or is black with the words "media selection request failed".
