// NOTE: The normal $(document).ready(function{...}); syntax for whatever reason doesn't work, worth looking into by someone. Shitty timer is shitty.

   document.querySelectorAll(".ytp-settings-button").item(0).click();

//Alternative Method - I've found gets overridden by the actual player, thus the timeout to wait around for the doc to load.

Can you make scripts that set a timer to automatically pause/stop on all Youtube embed videos? Like pause a video after X seconds!!?
