Xfinity website, live tv or saved will not play videos with FireFox 55.0.3 32 bit

Im having an issue with 2 windows 10 PCs and Firefox 55.03 and not playing video from Live TV or Saved (DVR) video from the Xfinity website.  In the xfinity site, I click on what I want to watch and the 3 dots just clock.    Both PC's I have the same plugins, Openh264 video Codec, Widevine Content decryption, and Shockwave Flash (latest). I even unistalled and reinstalled Flash.  Nothing.......  Sort of at a loss.  This used to work great from Firefox, now no longers.  Chrome and Edge seem to work fine.
