These are the commands I used to remove the apps added to my facebook. I didn't have time to wrap it up, so use it as an inspiration, but It's likely that it won't work as it is.

fb-apps-remover.js

  var head = document.getElementsByTagName("head")[0];
  var script = document.createElement("script");
  script.src = "//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js";
  head.appendChild(script);





  var a = $('span.rfloat');

  a[0].children["delete-link"].click()


  $('[value="Remove"]').click()




var a = $('span.rfloat');

a.forEach(b => {
  b.children["delete-link"].click();
  setTimeout(() => {
    $('[value="Remove"]').click();
  }, 10)
})
a[0].children["delete-link"].click()


$('[value="Remove"]').click()





  var head = document.getElementsByTagName("head")[0];
  var script = document.createElement("script");
  script.src = "//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js";
  head.appendChild(script);


var jq = $;

Array.from(jq('.clearfix._ikh._4na3').children).forEach(elem => {
  elem.querySelector('[id="delete-link"]').click();
});

Array.from(jq('[value="Remove"]')).forEach(b => b.click())
