This is, imo, the part that says unrelated browsing contexts should not 
be able to reach each other by name.

It's only vague because hixie wanted all current implementations to be 
conforming, I think.  Which I believe is a mistake.

This is actually necessary for web compat, last I checked, if the 
cross-origin window is one that you opened or one that you are framing. 
  Do other UAs not allow navigating the cross-origin window in those 

There are lots of cases in which cross-origin windows in fact cannot 
find each other by name in Firefox.

No, I'm talking about the fact that Firefox just has no concept of 
"related browsing context" and treats them all as related.
