(In reply to Francisco A. from comment #4) This website belongs to a (known to us) threat actor network that makes specific campaigns towards certain profiles, so I wouldn't take this as a random crash due to origin and privesc (second stage) we found after that. Wait, are you saying this is an exploit observed in the wild, rather than a crash? Was the privesc also targeting Firefox?
