Please look at
You will find some missing elements.
I tested this on IOS and it is a problem with https everywhere so you can turn it off from the lion settings in the top right I would guess that the problem is that the missing content is loaded from a http address so the shields blocks them for security reasons cc @luke.mulks
That makes sense. Yes if I deactivate https everywhere I can see the missing content. So it is more a feature than a bug…
