    document.querySelectorAll('.comtr.coll .togg, .comtr .togg').forEach(function (t) {
      if (t.textContent.indexOf('+') !== -1) {
        t.click();
        opened++;
      }
    });
    if (opened > 0 && guard < 50) {
      guard++;
      setTimeout(pass, 30);
    }
  }
  pass();
})();

Does this example work?

Snippets are useless without somewhere to paste them.

JustZix takes 2 minutes to install and runs your code on every matching page. No account, no payment.
