I seriously can’t believe I found this, I was going crazy trying to figure out what was happening. I had already reinstalled FF, created a new brand account, and found a temporary fix for myself. Not sure how relevant it is but this problem started for me after I was attempting to transfer my Google Play Music library to Youtube Music. I came across this Google support thread where people had the same problems after doing it which led me to believe that was the cause: https://support.google.com/youtube/thread/37004854?hl=en I’m wondering now if they are all just Kaspersky users as well. Btw, the temporary fix I found was going back to the old design of YT by using this extension: https://addons.mozilla.org/en-US/firefox/addon/old-youtube/ Using Kaspersky at the same time does work so I’m guessing a part of the reason is just Youtube’s newer design being janky with other browsers but those based off Chromium.
