Byron, could you please have a look when you are back? I'm wondering if this surfacing because of the changes in Bug 1591199. Unfortunately coomeet.com seems to be some sort of chatroulette variant.

It is possible this is a dupe of bug 1620844. Let's see if this resolves now that it has landed.

[Julien Cristau [:jcristau]]

No crash so far on 75.0b5, so that's a good sign.

Yeah, this is probably a dupe of bug 1620844.
