    since i moved to sierra i cant get you tube to work. it starts up and displays the you tube display. but no vids run. all i get a you tube frame with black inside. it says your computer does not recognise any video format.
    i am baffled. i had already installed flash, thinking that it would run automatically hmtl5.
    i am completely stuck.
    anyone who can help, please let me know what to do
