 Firefox ESR with uBlock on Debian 12 bookworm
Message-ID: <0e44552d55e78167fe404fc72ad991d6@posteo.de>

Package: webext-ublock-origin-firefox
Version: 1.67.0+dfsg-1~deb12u1

I have a problem with Firefox ESR and uBlock on Debian 12:
If I want to watch a Youtube video, Youtube newly shows a white error 
message on dark gray background instead of the video, saying: An error 
occured. Please try again later. (Playback ID: QzN...)
In German: "Es ist ein Fehler aufgetreten. Bitte versuche es sp?ter noch 
einmal. (Wiedergabe-ID: QzN...)"
Reloading the page can help and you can watch the video after that! But 
that's not always the case.
Cleaning cache and cookie does not change the situation. The installed 
packages are as up to date as possible.
Does uBlock maybe need an update in the Debian 12 package repository?

The browser console shows two suspicious error entries:

XHR POST http://www.youtube.com/youtubei/v1/player?prettyPrint=false 
[HTTP/2 400]
XHR POST http://www.youtube.com/youtubei/v1/feedback?prettyPrint=false

This happens too on Debian 13.
