Streaming no longer works with Firefox
I'm trying to stream at watch.cox.com. It's always worked perfectly well for 3 years now. But just over the weekened the streaming no longer works with Firefox browser. It works on Chrome but not on Firefox. I can only imagine that Cox did some software update which conflicts with Firefox. I am using the latest Firefox on a Mac laptop. The error is the page just never loads- see image.
Anyone else experiencing this or know anything about it?
