Works great for individual videos. When playing a playlist with the screen off, it always pauses 20 seconds after it moves to the next video. Once you turn the screen back on it continues.

Thanks.

This extension is one of the main reasons why Firefox is better than others

Thank you very much for this addon, Firefox! Now I can listen to lectures on my phone, without the need to keep the screen on and drain my battery. YAY!

최고

That's exactly what I was looking for. Thank you!

Pretty useless. Works for a few minutes but then the video pauses again. Very annoying to go back to youtube to get the video playing again. I have a samsung s7 edge and i was using the latest version of firefox.

I like it

It stops playing after some time when screen is off.

Firefox is the best..
