Hi, how to do (without installing addons) to let Firefox opening YT videos with the "old" flash player, instead of html5, as default setting? there are some keys in about:config or it is compulsory to accept html5 with firefox?

because I dont appreciate that html5, after 11 years developing, is still unable to support GPU acceleration (on a machine capable up to 4K at 30p via dxva2).

thanks. regards,
