Exactly what I was looking for. I like having YouTube videos for music in a separate window while working, and this lets me control the music in my primary window without distraction.

Would love to see this incorporated into FireFox so that it supports all websites playing media, but until then, thank you for this addon!

One issue: the popup window seems to get confused on YouTube when the next video automatically starts playing. The window shows the previous video name and is missing control buttons.

Great extension, but i'd really like if it had sidebar support, as currently i just have to put its url in floorps sidebar and it doesnt have an icon.

Works pretty much the same as chrome's version. A few differences is that you have to click on the name of the video instead of the box to go to the tab. Also if you have more than 6 videos you can't scroll to click whatever video is on the bottom. It kind of maxes out at 5 videos.

It would be cool if it could see videos with no sound, but even chrome doesn't do that as far as I know.

It works, thank you so muuuch, would love if there is an option to edit the transparency of the preview

I would like to request youtube music integration, but so far it works just the way I would wish.

It's insane how this isn't popluar !!

truly one of a kind addon, blows my mind how mozilla still didn't incorprate their version of this...

Finally someone developed this Chrome-like nice feature. I've tried to find extensions like this for months, but today I finally found it.

Thank you! I'm adding this page to bookmarks and I'm also downloading the .xpi file.

Discovered this add-on on the Mozilla Connect community and it works really well. I've tried playing YouTube and BBC and it works perfectly. It doesn't seem to work yet with YouTube Music or Apple Music, but I imagine that will come in time.
