// REVISION HISTORY
//  20240120 Google result links now contain a H3 sub-element so we have to go to
// the parent to get the A element.

(function() {
'use strict';

document.addEventListener('contextmenu', function(event){
  let target = event.target;
  //console.log("foo1"); console.log(target);
  if (target.tagName === 'H3') {
    target = target.parentNode;
    //console.log("go to parent:"); console.log(target);
  }
  // Check if the right-clicked element is a link
  if (target.tagName === 'A' && target.href) {
    let url = target.href;
    let testRE;
    let found = 0;

    // Define the regular expressions for each website
    if (found = document.URL.match("http(s|)://www.google")) {
      // console.log(found);
      testRE = url.match("url=([^&]*)&");
    } else if (document.URL.match("http(s|)://mail.google")) {
