Youtube music fails to load TypeError: Can't access property "bind"

[hxsnaatdev]

Describe the bug
YouTube Music fails to load/initialize. The page throws repeated unhandled TypeError exceptions originating from the extension's code while constructing ytmusic-app, and the player never finishes loading.

To Reproduce
Steps to reproduce the behavior:

1. install or have the extention installed and enabled
2. Navigate to music.youtube.com
3. Page fails to load properly; console shows extension errors
4. See error
   : [YouTube Enhancer] Constructing ytmusic-app: TypeError: can't access property "bind", Na(...) is null
   g custom-elements-es5-adapter.js:11

Uncaught (in promise) TypeError: can't access property "bind", Na(...) is null

listen player_es6.vflset/en_GB/base.js:6282
gp music_polymer_inlined_html.js:1714
...

Expected behavior
YouTube Music should load normally with the extension enabled.

Desktop (please complete the following information):

• OS: macOS Tahoe 26.3
• Browser: FireFox 147.0.3

Additional context
Disabling the extension allows YouTube Music to load without errors, indicating the extension's injected scripts are interfering with ytmusic-app's custom element construction (likely a timing issue where the extension tries to access player/element internals before they're initialized).

Can you provide your settings export and the version of the extension? The extension honestly isn't intended for YouTube music at all, I think it just so happens to load on it because of the match values in the manifest

seems like a pure nix issue. works fine on me too (on a non nixified firefox) but don't with the nix-store build,

experiencing the same issue. i was able to get around it sometime by loading into music.youtube.com/library. but the ui would usually break again soon after i stared navigating around a bit.

is there a way to get it to selectively stop loading on YT music?

zen browser (firefox 131.0.2 based)
arch linux

no unfortunately without modifying the extensions manifest

Hi I also have this problem on firefox version 152.0.6 and extension version 1.33.0. This error appended in the file is first time loading the page, maybe it helps if you need more info pls say, also maybe just add a toggle to disable extension for yt music, maybe also a quick toggle to disble for yt, so that you dont have to go into the extension browser settings... just like remove youtube suggestions maybe... thank you (sry for the inline feature request).
