Had updates on Sparky and Firefox this pass week now can no longer view you tube videos. some have sound but no video and some have neither. So need to learn weather it was the Firefox or Sparky update that cause this. I have 3 different Sparky installs plus Zorin, Slax, and Rebellin. 2 of the Spark's I never update. will see if I can figure this out and will post back.
