Get the cinema experience in your browser with Turn Off the Lights
Turn Off the Lights is a browser extension that lets you watch videos on sites such as YouTube under proper cinema conditions. When you play your video, just click on the extension’s lamp button and Turn Off the Lights will automatically darken the rest of the screen, letting you watch your video with a minimum of outside distractions. You can adjust the darkness and opacity as well as enabling other features of your favourite online video player. This app provides an attractive cinema viewing experience and cuts down on eyestrain, especially when watching videos at night.
