hi, I am having trouble with facetime on facebook. the other person can see and hear me but I cannot see or hear them. my camera and microphone settings are enabled for facebook but i found that autoplay had block microphone and camera was showing after your update. so I set it to allow and facetime worked perfectly. today i came online and checked all settings were correct and they were, so I went to facetime to my sister and the same problem is back. I cannot hear or see them but they can hear and see me. what is going on firefox, why isn't this working when it shows that my camera and microphone is allowing permission for facebook.
