// 1) get all links

var allLinks = document.getElementsByTagName('a');

// 2) create a new array for the links that we want

var myLinks = [];

// 3) walk through all links and add their addresses to myLinks array only if they match

for (var i = 0; i < allLinks.length; i++) {
   if (allLinks[i].href.match(/\/s\/.*\/1\//)) {
      myLinks.push(allLinks[i].href);
   }
}

// 4) create a new div element, insert it into the document and display the links there

document.body.insertBefore(document.createElement('div'), document.body.firstChild).innerHTML = myLinks.join('<br>');
