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.
Rank: 35
Priority: -- → P4

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.

Nils, if this is still non-reproducible, should we close out the bug?

This site is using WebRTC for tracking users. The originally reported error is gone.
