It works!

Im not sure it's supposed to have any effect on Desktop Firefox, but somehow it's fixed the issue I was facing - the url bar PiP button was constantly vanishing on youtube/displays despite the PiP right-click and floating button working fine

This extension seems to fix that perfectly as well!

Thank you so much for making this extension, this works perfectly for playing YouTube videos my device.

awesome extension. the picture-in-picture works the same as the Google version but with more features, which is just what i was looking for.

Extension works so no longer have to deal with YouTube trying to break itself on Firefox instead of fixing their own app's memory leak issues.

I had no idea that YT intentionally broke PiP on android. It's been bugging me for years. This extension works perfectly, as far as I can tell. I've been running into a problem where the video stops loading and thus stops playing, and I have to reset the PiP window, but that may just be an Internet issue, and not the extension.
