Do Browser extensions work also in the PWA window?

Yes, and you have a look and feeling like the website is an app on your computer. That with no address bar or tabs strip in the window. The app is in reality a web browser and so the Turn Off the Lights browser extension work here too.

What is PWA?

PWA or Progressive Web Applications are web apps that work and function like native apps, although they are built using HTML, CSS, and Javascript like regular web pages do. Websites with PWA support are intended to work on any platform that uses a standards-compliant browser, including both desktop and mobile devices.

How to install PWA?

It is very easy to install a PWA. For example, when you are on the website you will see in the address bar (in Google Chrome) an extra icon like a computer with an arrow point downward. When you installed the App, it will be added to your installed applications page (for Google Chrome at chrome://apps).

When you open a PWA you see the window with the website content such as But on the top left of that window, you see the puzzle icon. When you click on this icon, you can choose the Turn Off the Lights browser extension and any other installed browser extensions. And it will dim the web page and highlight the video player. Also, other content features such as AutoHD (720p, 1080, 4K, 8K), Atmosphere Lighting, will work in the app window. All browser extensions will work just like in the regular web browser mode.
