If you use enlarged player that covers the whole viewport and scroll away, there's no option to perfectly focus on the player again. I wrote this simple JS, so when you middle click anywhere on the page it scrolls right where the player is (should add some functionality that allows that by default in your addon)

document.getElementById("content").addEventListener("auxclick", function(event){
if(event.button == 1)
document.getElementById("player-theater-container").scrollIntoView();
});

Отлично

Good enough extension. I note that the Auto-pause for the background tabs, doesn't work. Pause videos on the backround tabs, when a video in the foreground tab starts, works fine.

Very good add-on. Please add screenshot capture!

just awesome

Really amazing, but, I wish the toolbar was completely optional to remove.
