I notice something strange about group chat didn't pop up, so I went check it out random chat what I have and I don't see group chat show up on bar. I did check option and nothing on the list. What happen to group chat? Nobody told me what happen or what is cause group chat vanish in the air. I did look up help facebook and none of them mention how is that happen. So I am struck with it. Any idea how is this happen? Edit - Oh, I forgot mention. I use Firefox.
