i learned YT launched a new player/layout when i opened a YT tab in the background and immediately experienced ear-killing full-volume fury. my YT-taming userscripts/add-on were no longer functional

just for due diligence i checked youtube's settings menu for a remedy but the situation was even more dire than i expected

a site about heckin' watching videos that barely lets you control the video player. at least don't autoplay when the tab's not focused, geez
