This website, and others like it, have pop-ups in the page that firefox plays a strumed-chord notification sound for: https://dcist.com/story/22/12/12/weekday-events-12-12-2022/ I've gone into site permissions and default blocked audio and video autoplay, blocked notifications, everything is set to ask to allow orblocked. The website does not have exceptions. I've tried blocking all notifications in Firefox settings and in my android app permissions for Firefox. Nothing will stop this obvious trill when popups are triggered. How do I block this noise? I am running Firefox on Android 13 pixep 6a 107.2.0 (Build #2015918523), 1490acda7+ AC: 107.0.8, e189e99662 GV: 107.0.1-20221128144904 AS: 94.2.2
