Are you sure that regression range is correct? I don't see anything in there that should cause this.

Also is it just an error message or is the website actually broken?

Oh wait that's a WebRTC thing so could be bug 1425780.

Nils, is there someone that could take a peek at this?  I tried it here, but it doesn't happen for me in Nightly or a local build.  In fact, really nothing happens on the page for me aside from a dark gray rectangle.

Putting this as low priority until we can confirm this is a problem with Firefox and not with the site. For what it's worth, I only see a grey rectangle as well, even with content blocking disabled.

Yes I can't reproduce on my end either (I see the loading screen and eventually it changes to a grey rectangle).

Since the page is showing quite bit of advertisements my guess is the errors on the console are caused by advertisers trying to leverage WebRTC to track users.
