If you use the Turn Off the Lights browser extension, you will see the gray lamp button in your toolbar. If you click on the gray lamp button it dims the whole web page. And if there is an embedded YouTube or HTML5 video on the web page it highlights that video player. But as an internet user, you dim not the whole screen, and also not the menubar is not dark. It is screen dimmer for all in your web browser screen only.
Where screen dimmer that dims the whole screen to black?
