A JavaScript snippet for removing likes on public statuses on Facebook. Operates on the mobile site (https://m.facebook.com/<you>/allactivity?log_filter=likes) by searching for lines with a "Public" tag. You need to expand times to search first.

ActLogPubLikes.js

// for all public tags
$(".sx_c87e68").each(function(i, e) {
  // navigate up to the root of the item
  var r = $(e).parent().parent().parent().parent().parent().next();
  var id = r.parent().attr("id");
  // open the dropdown
  r.find("i").click();
  // find the corresponding menu
  $(".accelerate").find("a").each(function(j, l) {
    if ($(l).data("store").domID == id) {
      // click the "Unlike" option
      $($(l).find("span")[0]).click();
    }
  });
});
// click all the "Load more" links
$("._3nt5.sectionContent._56d8").click();

Can you include some instructions on how to use this with tampermonkey?
