// Thanks to @montavilla for pointing me toward Neal Wu's Chrome extension, Kill News Feed (https://chrome.google.com/webstore/detail/kill-news-feed/hjobfcedfgohjkaieocljfcppjbkglfd), which accomplishes the same thing using jQuery.

  var feedSelectors = [
    'div[id^="feed_stream"]',
    '#pagelet_trending_tags_and_topics',
    '#pagelet_ego_pane',

  ];

  feedSelectors.forEach(function(feedSelector) {
    var feed = document.querySelector(feedSelector);

    if(feed) {
      feed.parentNode.removeChild(feed);

var observer = new MutationObserver(function(mutations) {
  mutations.forEach(function() {
