as this doesn't work in the sceneDuplicateChecker admin tool page, I've added a second layout for this and also disabled the help popup. This would be better as an actual plugin for stash incorporating https://github.com/vivictorg/vivict to run without internet access and even better as a modal on the page rather than fullscreen, but I have no idea how to implement that.

Might this is of use to someone.

function compare() {
    if (window.location.pathname == "/sceneDuplicateChecker") {
      var numberOfChecked = document.querySelectorAll('input.position-static[type="checkbox"]:checked').length;
      if (numberOfChecked == 2) {
        var lr = []
        const list = document.querySelectorAll('input[type="checkbox"].position-static:checked')
        for (let item of list) {
          const row = item.closest('tr');
          const nextAnchor = row.querySelector('a');
          const url = nextAnchor.getAttribute('href').replace(/\/scenes\//g, '/scene/')
          lr.push(window.location.origin.concat(url))
        }
        var site = "http://scruffynerf.stashapp.cc"
        var url = site.concat("?leftVideoUrl=", lr[0], "/stream&rightVideoUrl=", lr[1], "/stream&hideHelp=1")
        GM_openInTab(url, true);
      }
    } else {
      var numberOfChecked = document.querySelectorAll('input[type="checkbox"]:checked').length;
      if (numberOfChecked == 2) {
        const r = /[^"]+\/scene\/\d+\/s/ms;
        var lr = []
        const list = document.querySelectorAll('input[type=checkbox]:checked')
        for (let item of list) {
          var urlstuff = item.nextElementSibling.innerHTML
          var m = r.exec(urlstuff)
          lr.push(m[0])
        }
