youtube playback speed not working after update 11-12-2025

YouTube has been a problem for some time. I was getting this (see screenshot) and had to go [https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode# Troubleshoot mode] for it to work normally. It felt strange to finally see that YouTube red progress bar go across the browser.

Had to turn off ETP, Adblock Plus, and Ghostery for it work normally. see screenshot
