Sometimes it doesn't work 😭
I must have to open Firefox again to let the video play again...

Oh,and I hope it can use on YouTube music too!🤩
Not only can use on youtube.com

Works really well with YouTube—I can play videos in the background for hours with little to no issues. It doesn't work so well for YouTube Music, however. I can play music in the background, but it will freeze up after every song, sometimes in the middle of the songs, and I have to re-open Firefox to get it playing again. Great overall, but if it was updated with better YouTube Music support, I'd give it a full 5 stars.

it only occasionally works

Not working with the extension youtube utils

《UPDATE #2》
I believe I have discovered the issue! So, as stated in the 1ˢᵗ 2 reviews below, the app works on SOME videos {+5☆}, but on OTHERS it gets cut off as the page reloads {-4☆}.
After some experimentation, I can now definitely confirm that this extension functions EXACTLY as advertised on any "normal" video/playlist (like when listening to a podcast, for example).
HOWEVER, for any video YouTube has flagged as MUSIC, it forces the browser to kill the tab, automatically reloading it when next you switch over to it.

SO THERE YOU HAVE IT, MY DEAR SWEET DEV-TEAM! I've officially located the issue for you. NOW, all you gotta do is fix it.

As for my review... since I've proven the Extension still has ~50% functionality... {+2☆}, bringing the current total up to a respectable 3☆.
That said, should you release an update solving the music issue, I'll GLADLY bumb that badboy back up to 5☆!

Lookin' forward to it.

《UPDATE #1》
Not sure what happened, or if it's just on certain videos, but it definitely started failing every 5-10 minutes...
As soon as you fix that issue, I'll change it back to 5☆ though!
(it's so weird, cuz it literally just worked like 14 hours ago...)

《ORIGINAL REVIEW》
Perfection. It does EXACTLY whst it says it'll do. YouTube/Mozilla keep putting out updates that makes it harder and harder to multitask or listen to videos, but THIS is the solution.
THANK YOU.

Doesn't work when I close my phone screen

Will only work about 1/2 the time and almost never until the video loads a for a bit

On my phone after 5 mins the youtube video pauses again. The app is an excellent idea, not sure if my device is the problem, tested on firefox v113.

It used to work great until a couple of days ago. Perhaps youtube is learning to avoid people trying to leave their screen off. Please fix this app, it used to be a blessing. 🙏

e bom mais tem melhora mais.

I am sad that i have to give this fantastic app three stars only. This is, because for me presonally it often so happens that when I try to have a youtube video running in the background. This happens in both cases, when minimizing the firefox app or locking the phone. Retrying for one or two more times resolves the issue. I am using a Redmi Note 11 and firefox v110.

怎么用？
