Will this work with YouTube embedded and external Videos?

Yes, Turn Off the Lights detects all the YouTube embedded and external video players on the web. Furthermore, if you are on a blog, news website, or any other website, the Turn Off the Lights browser extension will detect the video player on that web page. And then click on the gray lamp button in your toolbar, it automatically highlights that HTML5 or Adobe Flash video player.

Default supports the Turn Off the Lights browser extension for the following video websites when you dim the web page:

If it can not detect the video player container well, therefore enable the “Flash Detection” feature in the Turn Off the Lights Options page – Advanced Options – Flash Detection. As a result, this feature will search for all the “object“, “embed“, “applet“, and “iframe” elements, and push those elements on top of this dark layer.

However, if for some reason the Turn Off the Lights Browser extension did not detect well the video player on that web page. In addition, to enable the Flash Detection feature, try to disable the other browser extensions you are using one by one except Turn Off the Lights.
