Unfortunately, the extension doesn't work correctly anymore. It seems to extend the time the video plays somewhat, but it still stops after a while. At the same time, it's got a bug where a YouTube tab can enter an indefinite reload cycle.

With this extension enable any playlist I try to listen to does not play in sequence and instead jumps around up and down the list as if I have shuffle toggled on. Weirdly this does not happen with the Google Chrome version of this addon by the same developer.

It works perfectly on my laptop, and on Firefox Nightly!! I wish it was available for the stable version of Android Firefox though, because YouTube lags and has audio glitches on nightly, even without the extensions enabled.

This makes your playlist always play in shuffle mode. What's the point of using it then...

Puts youtube into a refresh loop.

put youtube into a constant refresh loop, which i could only stop by removing it.

Doesn't work anymore since YouTube changed their lay-out. It does not loop or shuffle playlist. Also the play/pause button got stuck after a long time playing a video in the background
Found another one that works: YT Nonstop (is has 'ytnonstop' in the url and is made by JohnyP)

AutoLoop and AutoShuffle not working now....is it because Firefox update?

Disable Autoskip, AutoLoop and AutoShuffle don't work for a very long time.

Causes Firefox to use 30-40% of CPU and use +14GB of RAM. Completely unusable.

Not open source. Why??

Returned to 1.7.0, autoloop for playlist is not working properly, and there is no option to disable it and not override YT settings. FF 87.0 32b. It is next time i wish i had disabled autoupdate for any addon. Even if it is for free i still dont feel right to be a betatester because author clearly didnt test it at all.

2023 Still working as advertised completely controls that irritating message and plays on...

I would give it 10 stars! Finally, a great solution that actually works!!! Deserves the donation ;)
