It works very well I used it to watch Youtube on my second monitor.

Excelente, tan buena como se puede esperar.

update 29/06
extension is working for me again
a great convenience feature for video websites, especially youtube where without this, i'd have to right-click the video twice to pull up PiP
also works on some sites where i cant right click for PiP at all normally

Works perfectly. Great add-on for multi-tasking. Thanks...
Edit: Works flawlessly on YouTube.

no idea why it has so many 1 star, maybe many people dont understand how to use it. its way better than the google extention cus on this one you can scale to it any size. i prefer this one way more than google.

5/5 very pog

i am unsure why a few users are saying it doesn't work, it works as intended, when you start a video a small square will appear in the lower right corner, this is how i use it anyway, though if it were possible for a feature when watching episodes that would be great.
