Hi :-)

Could you explain how to use it, please ?
It doesn't work if I do nothing.

Click extension icon to toggle enable/disable. screenshot is available in firefox addon page
If it it doesn't work, you are unlucky. I think youtube may be testing new changes, it delivers different pages to user randomly. That's why extension is not working on every user's environment.

It you have good solution, I can merge into this extension.

I second this request for some documentation on how the extension is meant to work .

I cannot get this extension to work at all with Firefox Developer Edition v129.b9 for Linux (Fedora-40) x86_64 .

No version of the extension works with Live Videos from the YouTube page - you must right-click on the video,
click on "Copy Embed Link", and create a little HTML file, like, for example my test page :

  ``` <!DOCTYPE html>
       <html>
       <head>
       <title>Neutrality Studies, Pascal Lottaz</title>
        <style type="text/css">
          .centered { display:block; margin-left:auto; margin-right:auto; }
       </style>
    </head>
    <body>
    <iframe width="1280" height="720" src="https://www.youtube.com/embed/i6RY3If2ex8" title="The Neocon&#39;s WORST Nightmare Is Coming True: A United Asia | J. Pang and Naoko Kumada" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" referrerpolicy="strict-origin-when-cross-origin" allowfullscreen  class="centered"></iframe>
   </body>
   </html>

The "<iframe> ... </iframe>" is the "Embed Link" I got from YouTube player page .

I have to NOT watch any video or audio on the YouTube Player page anyway, since
the Live Chat and persistant attempts to diplay AdWare from sites I redirect the DNS
lookups to '0.0.0.0' for, with ISC BIND named Response Policy Zones (RPZ),
this consumes too much CPU already and I always create little HTML pages with the
Embed Link pasted as above anyway . I usuually DO NOT want to sit watching such
videos, I like to listen to news / current affairs discussions in the background.

I was able to install the Chrome Extension "Audio Only YouTube" v0.10.0 in google-chrome-unstable
(Chrome version "129.0.6614.3 (Official Build) dev (64-bit)") .
This works perfectly - a banner title appears above the Video Title :
"Audio Only . To watch video, click on Extensions Icon above and refresh the page."
and no video appears ! Great !
I am investigating with WireShark / TCP Dump as to whether the extension's claims NOT to actually download the video
at all are true - is this actually possible with a normal YouTube MP4 video ?

Why doesn't your extension work similarly under Firefox ?

So the important part is that it requests :
mime: audio/webm
right ?

It would be most interesting if you could share any information / sources to documentation about the derivation
of the above videplayback URL parameters -- Thanks !

This extension is chrome extension ported to Firefox. I make some changes only. I requested document from original author but no answer.
Live stream is not supported.
This extension tries to replace video element's url to first found audio not limited to webm. It will play video if it can't find any audio or it's live.

Thank you very much. :-)
It worked for a while.

Now, it does no longer work.
Is it the same for you? Do you know what has changed?

Does that mean it's useless to request new features?

Almost true

I think this extension is dead. Original chrome version is not working.
Youtube will prevent user to do this without premium, they want user watch ads.

Youtube will prevent user to do this without premium, they want user watch ads.

Do you know if they do that by joining audio and video into the same stream even when they are separate at origin?

If yes, then the network bandwidth is wasted, but we can still save CPU time. Firefox already does it when the tab is not open.

Tell me if the API doesn't allow that!
