When I directly tap on a youtube video from listings it plays the video, but if I open in a new tab, or open a previously opened tab, or reload the page, it is stuck on a silver loading circle. I have tried on chrome and adblockplus browsers and I see the same circle but then the videos will play. It seems youtube recently updated their site to autoplay videos with the tap to unmute as the first tap and then tap again to bring up controls and then tap pause to stop the video. But only on firefox is this a problem. I have posted in youtube help forums but wanted to post here as well.
