Okay, so I've been on this for hours and I'm getting frustrated. I've been watching a TV show on Netflix and looking through Tumblr. The sound comes from Netflix but when I found video on Tumblr it plays nothing, I go to YouTube nothing comes out. I restarted FireFox, removed Flash and then downloaded it again. I don't know what to do. Help!
