Good Add-on, very useful!
It can do this
- YouTube Background Play
- YouTube PIP

Thank you for making this available.

If you listen to music on youtube, this allows the music to continue playing when you to turn the screen off or go to another tab or app.

You can achieve the same result by going fullscreen on video, then going to home screen (forcing the video to be in a pop up frame), then turning the screen off, turning it back on (you now have a lock screen) and pressing the play button. But this addon just saves you a lot of time

top notch

Just installed this on Firefox for Android. Perfect!!!

YouTubeを開き、再生したまま別のタブへ移動しても再生が続く。
またfirefoxを閉じても可能。

полезная программа, удобно

Thank you!!!
