Auto-play video with sound is allowed by browsers after you interact with a web page. Youtube is an SPA (you can tell because it often fucks up the back button) so when you click on video link, you're interacting and auto-play works. When you open in a new tab, it loads anew and won't auto-play because there hasn't been any interaction. https://developer.mozilla.org/en-US/docs/Web/Media/Autoplay_guide https://developer.mozilla.org/en-US/docs/Web/Media/Autoplay_...
