September 7, 2019 I was not able to block videos from automatically playing on the ESPN website. Operating system = Windows 7 - 64 bit Firefox web browser version 69 is installed and the Autoplay feature was set to Block Audio and Video. I closed Firefox and restarted my system. I made sure the Block Audio and Video selection was still enabled. I went to the ESPN website, selected MLB from the pull down menu and selected SCORES. From there I picked any game that was played and selected BOX SCORE. The summary page for that game displayed on the web page and the small autoplay video screen to the right began to play (without sound). I noticed that if I selected the "circle I" from the address bar and then selected "Clear Cookies and Site Data ..." at the bottom of the pull-down menu, I could clear two cookies (espn.com and www.espn.com) and then the autoplay video screen would be blacked out. But this work-around is required every time I visit the ESPN website, which defeats the purpose of the new video blocking feature of Firefox version 69.
