i'm not sure if it works, i feel like i need a visual guide to know what changes more than just the one screenshot

does not work

It all works fine again, except there's no youtube livestream chat.
There is a message
"Oh no! It looks like you're using an older version of your browser. Please update it to use live chat."

Would be nice, if you can fix this.
I'm using Firefox 77.0.1 newest Version ,64bit
Great Addon.

Seems to be only addon that actually works for this purpose, except it stopped working 6/16/2020. Choosing "Old layout" either through its own button or its dedicated settings panel inside the addon manager only breaks the YouTube page. Tried clearing cache, restarting Firefox, temporarily disabling all other addons - still nothing. running Windows 7 64-bit, Firefox 56.0.2 64-bit.

This extension worked well but now it doesn`t work. Could you fix it?

This extension is essential. Thank you!

It works with a small issue. The settings can just be made in the addons section because when I leftklick the icon the options do not contain any text. FF60.4 portable, 64-bit

- work like a charm
- pretty decent sourcecode without obfuscation
- only access to youtube.com domain
this is a 5/5 ! ;)

It's absolutely brilliant

10/10
very well done sir :D

This addon fixes the YoutubeCenter script. Awesome!
