Very Weird issue with firefox xfinity live tv when kodi is open

So, this just started to happen a few days ago but here is the situation. I have shortcuts (.ink) used to open comcast xfinity live tv (in firefox) using advanced launcher. Everything launches fine I select a channel to watch. It loads and then its it just frozen. No sound just a static image is displayed. I troubleshooted it down to having kodi open. If kodi is closed, accessing the same channel using the same (.ink) the channel plays fine. I have done this a 10 times to see if it was a fluke but everytime same thing. Now, if I open using chrome there is no issue playing the channel. The problem with chrome is that it has audio issues playing over HDMI (most of the time no sound, take some toggeling to get it going so its a headache). Does any have any clue at all what could be causing the issue in firefox. I have updated the flash player and well as firefox itself and still the same problem. Any help would be appreciated!

Cheers!
