Turn Off the Lights™

Fade out the ads on your You Tube videos by adding this extension to your Chrome Browswer

Turn Off the Lights is a browser extension that lets users obscure everything on their screen except the Flash or HTML5 video they're watching, minimizing distractions and making for a more pleasant viewing experience for the users. A lamp icon is displayed in the browser menu bar or in the omnibox, and users click on the gray lamp icon to make the area surrounding the video fade. Clicking outside the video restores the rest of the screen. Users can adjust the opacity of the screen blocking and select a color other than black if desired.
