function forEach(list, callback) {
    Array.prototype.forEach.call(list, callback);
}

var cleanupResults = function() {
	forEach(document.getElementsByTagName('cite'), function(o) {
		if(o.textContent.indexOf("w3schools.com") > 0) {
			var node = o.parentNode.parentNode.parentNode.parentNode.parentNode;
			node.parentNode.removeChild(node);
		}
	});
}; cleanupResults();

var observer = new MutationObserver(function(mutations) {
  mutations.forEach(function(mutation) {
    cleanupResults();
  });    
});
 
observer.observe(document.body, { childList: true });

This wasn't working for me as is so I added a gross timeout:

var i = 0;
var cleanupResults = function() {
    if (i > 1000)
        return;
    
	forEach(document.getElementsByTagName('cite'), function(o) {
		if(o.textContent.indexOf("w3schools.com") > 0) {
			var node = o.parentNode.parentNode.parentNode.parentNode.parentNode;
			node.parentNode.removeChild(node);
		}
	});
    setTimeout(cleanupResults,15);
};
