Video doesn't work on certain sites like CNN, Crackle, ESPN, CBS, and others. It still works on YT.

Question

On CNN there's just a white space where the headline video normally is, and there's just a black space in the videos section. In Crackle there's just a black space when I click to watch a video. On CBS the little eye logo keeps processing over white space and doesn't load. One curious thing I noted is that the login and help buttons don't respond on CNN, even though I can navigate within the site

Hello,
Many site issues can be caused by corrupt cookies or cache. In order to try to fix these problems, the first step is to clear both cookies and the cache.
