Do you want to dim the screen automatically when you click on the play button on the HTML5 or YouTube video? Enable the autoplay feature in the Turn Off the Lights browser extension. And now when you click on the play button, it dims automatically the web page and highlight that video player. Also if you pause the video, it fades automatically back to the normal view of the website.
