The popout player doesn't show up over other tabs or windows so it's basicly useless.
However i have found that mozila already has an inbuilt popout player called picture-in-picture but it's kinda unintuitive to reach for some reason. You can double right click or shift right click on a youtube video to bypass youtube's fancy right click menu and reach mozila's right click menu. In mozila's menu you will have an option that saies something along the lines of "watch with picture-in-picture", idk exactly how it would be in english cuz my menu is in romanian so i'm having to translate.

Can resize the screen to be very smol, can do work while having a video in the corner.

Great stuff. It would be good if on selecting the popout player the windows minimizes to the task bar.

Extension does exactly what Firefox USED TO DO AUTOMATICALLY.

Currently, Firefox "Pop-Out" video player doesn't work on sites other than YouTube.

So, effectively, virtually useless.

This disabling of former Firefox features is, of course, because of the internet wide and Worldwide software plague of making NEW versions of things WORSE than the versions they replace (I'm looking at you, Windows-everything-since-Windows 7.

fantastico :)))))

Wow amazing !! Finally I found the Desktop version of the PopUp Player YouTube Add-ons. I've been a fan of Mozilla Firefox since its inception. Although these add-ons are not at the very top of the search for add-ons, but after I use them they work very well as expected. Of course there are a few configurations that must be adjusted to suit your needs. Its name is YouTube Popout Player (not Popup Player) but the purpose and function is the same, namely being able to play the YouTube Mini Player flying over anywhere in Windows. Thank you very much for the creator of these add-ons as well as Software Developers, it is really very useful. Love From 🇮🇩 Indonesia.

This add-on does exactly what I was looking for. It always annoys me that Youtubes miniplayer disappears when switching to a new tab. This popout player solves that problem and does a great job!

Amazing, just what I was looking for, love it!

Great, the only lacking feature is to be able to place the button icon on the video preview to have the opportunity to run video from the main page.
UPD: Yes, I know, but I would like to open the video in one click, as in this addon Popup Video(WebExtension).
Thanks for the excellent addon.

Perfect, the only lacking feature is to be able to place the popup when choosing a custom size.

Works well, except on videos where the video ID is not in the URL itself (i.e. live streams). Example: https://www.youtube.com/c/euronews/live

been using this for ages plus a program called DeskPins that allows you to set a window to be always on top. (theres a setting that allows you to put a custom string in the window title that deskpins can search for) Unfortunately for the developer Firefox enabled functionality that makes this method redundant.

Served it's purpose well. No longer need it now that Firefox supports Picture-in-Picture.

doesn't works

I gave it 3 because the lack of "stay on top" and this one issue....

if you have the window open and then force quit Firefox for any reason then when you re-open it (with the restore session checked) the pop out window is now missing the "top bar" and you cannot close the window.

Really great implementation, 5 stars if you can find a way to also ship it with "always on top" functionality. ;) But with five minutes of work on the individual's part, they could easily implement that themselves. Look up autohotkey and always on top in the same search folks. I'm not even sure add-ons for firefox can do something like that my self, considering that's more to do with your operating system than your web browser, lol.

Need "Always on Top"
