The entire page will be fading to dark, so you can watch the videos as if you were in the cinema. Works for YouTube™ and Beyond. With a single click on the lamp button, the page will fade to dark. And automatically focus on the video. By clicking on it again, the page will return to normal.

Hi everyone, It is finally here, the Turn Off the Lights for Safari extension and with the powerful Double Click Menu. The Turn Off the Lights for Safari app works well together with the macOS Mojave dark mode. For example, when you dark mode is enabled, the Turn Off the Lights Options page will be also dark. 🌚 The Turn Off the Lights for Safari extension is 100% free. And we don’t charge you to get this extension in your Safari web browser. As we believe this tool must be available for everyone, from students to teachers, and users who want to protect his eyes against this bright white light. If you like our work, please make a small donation to keep this free and open Source Turn Off the Lights available each year: https://www.turnoffthelights.com... Thanks, Stefan
