hello, Please help. I think I turned off something or blocked some feature that allows you to see the video on certain web pages. For instance. When I go to Dr. oz's page. i know there is suppose to be a video there. It does not show up on my web page. I have a black white space. I can see Youtube videos and I can watch netflix but for somereason, I blocked some feature and I don't know when or where or how to unblock it. Please help so I don't have to go stand in the apple store for hours. just checked. this only happens in Firefox. When I go to the page in Safari, I can see the video.
