With extensions YouTube on Firefox is almost better than native app, but it doesn’t have any pop out player which is I often use on native app, if anyone know how to to that please do tell.
I don’t know if it’s a premium feature or not, but this is native to YouTube under playback settings. It automatically goes to pip when you switch apps.
No I mean for YouTube on Firefox browser
Not sure if this is universal, since I don’t think I have any add-ons. But I open the video, put it in full screen, and then swipe up quickly from the very bottom bar of my phone and it goes into PIP view.
Did not work for me unfortunately (Iceraven)
On Desktop Enhancer for Youtube has this - https://addons.mozilla.org/en-US/firefox/addon/enhancer-for-youtube/ Though I thought Firefox had Picture-in-picture as a browser feature… I can’t remember since I never use(d) it.
But clearly you’re asking about mobile. No idea if this or any other extension is supported there.
