I had been having issues with my pc so did a factory reset. I reinstalled Firefox and now Youtube videos WILL play but nothing else. I have done everything in the suggestions, disabled add ons, and unchecked the accelerator whatever under performance. Still nothing. BTW all vids play fine in Edge, Google chrome etc. It's just Firefox. Thanks in advance.
