Stream dose not load or often reload and become can't hear sound.
But same extention works fine at Edge.

Same refresh problems as already mentioned.
Otherwise could be a very useful add-on.

As others have stated - the extension will refresh youtube videos over and over (every 5-10 minutes).

To replicate: play this 'multi-song' video for ~10-15 minutes. at certain point, the video will; refresh, and start playing at 0:00

Seems to indeed not load the video. However as stated in latest comments, refreshes the videos after a few minutes, so useless as of now.

This extention no longer works as of Aug 22, 2021. It will keep refreshing the video over and over again.

Very good but I think it would be a good idea to have this work only in current tab/window, for example if you were to watch a video while playing music in the background, you should be able to have video turned ON for one of them and OFF on the other one.

it does turn off the video and is audio only, but it wont awitch off except in the add ons control menu firefox 88.0.1 I have to disable it when i want to watch videos.

this one and unhook youtube are my favorite plugins. i'm too poor to donate but when i work as a programmer i'll donate

So ergonomic. Thank you.

It doesn't work anymore.

Just works and saves a ton of energy streamingwise :)

all other audio-only-youtube doesn't work when upgrading to Firefox 74.0.1
This is the only extension that works well, even shows the subtitles while audio-only is enabled
Using Firefox 74.0.1 on Debian unstable amd64

Works perfect for Firefox desktop, but ia a corrupted file for Android. Hope it gets fixed
