It works!

Simple and efficient - Love it !

Best Pop out/ Picture in picture player. Thanks Dev.

For anyone missing ALWAYS ON TOP feature. There is small utility which I run automatically with Windows startup. Hitting CTRL+SPACE will make any window to be ALWAYS ON TOP. It is useful not only for video popup but also if I need Excel, terminal or anything to be always on my screen. Download here, no install needed:

Coming from Opera I missed the popout video feature. I tried few add-ons that did not work at all before I found this one. This one works flawlessly, and the setting to chose pop-out video size makes it better than anything I tried so far. The only thing that can get better is the icon used, but this is nitpicking.

Works great!

Great extension!
Thanks!!!

感謝持續開發優秀實用的套件。

Espectacular muy útil para varias cosas, buscaba algo así porque es una de las pocas funciones que tiene opera que no tiene firefox y me parece útil, aún así hay sitios que no te permite hacer popup (aquellos que utilizan flash o videos mediante plugins o tienen DRM), otro detalle es que estaría bueno intentar que la ventana popup se mantenga sobre todo, en linux no hay mucho drama uno lo puede configurar, pero en windows se complica. de todas forma gracias por el esfuerzo!

best pop up player on firefox... You don't have to go inside the video, just click on the right top corner icon and that's all :)

Best YouTube Pop out video widows i have found.

It's very convenient to watch videos while the main focus is on something else. Especially cool is the ability to open a window by clicking on the icon. Make a window pinned on top of screen and it will be best add-on.
