Dude...I finally switched from Firefox ESR version which kept all of my old reliable add-ons working (Flashstopper, Classic Theme Restorer etc.)..I STILL really miss the addon/search bars that CTR gave me & ability to use text for the icons among many things but the Youtube autoplay in this new version was killin me..This new Chromed up version of FF still annoys me but I tried Chrome and hated it even worse but ESR release was slowing down awful...tried a bunch of about:config hacks and some other addons here but only yours works for killin YT Autoplay..I am adding some money to my Paypal account to buy you a beer brother...god bless the developers
