Just installed 81.0.2 update, did not install cleanly, had to reset. All privacy & security settings were wiped. Redid everything, am now unable to block videos on news sites, which I had done previously. Can block autoplay with following config settings - media.autoplay.allow-extension-background-pages - false media.autoplay.block-event.enabled - true media.autoplay.block-webaudio - true media.autoplay.blocking_policy - 1 media.autoplay.default - 5 Can no longer block videos from loading. How to do this in 81.0.2?
