If you're annoyed by the floating, screaming video player that haunts CBSNews.com pages, here's a Greasemoney script I wrote to kill it:

// ==UserScript==
// @name         CBSNews Floating Video Killer
// @include      https://www.cbsnews.com/*
// @grant        none
// @noframes
// ==/UserScript==

setInterval(function handler() {
  
  // front page
  var frameDiv = document.querySelector(".embed__content--draggable");
  
  // article
  if (frameDiv == null) frameDiv = document.querySelector(".media-block");
  
  if (frameDiv != null)
  {
    // are we looking at the floating frame, or the header player?
    var floated = false;
    var classList = frameDiv.className.split(/\s+/);
    for (var i = 0; i < classList.length; i++) {
      if (classList[i] === 'floating') {
          floated = true;
        break;
      }
    }
    
    // don't touch the header player's button
    // (or you'll never be able to play it at all!)
    if (floated) {
      var element = document.querySelector(".player-overlay__button");
      if (element) {
          element.click();
      }
    }
  }
  
}, 1000);

(really just posting this here so I can share it between my own computers)
