I have a website that loads some external scripts. Those scripts generate dynamic website contents, such as adding a form into a div container.

However, only in Firefox, some scripts fail on the initial page load and the container element stays empty. There's no error in the JS console.

The weird part:

When I have the browsers Developer-Tools open, the website always works perfectly. But as soon as the Developer-Tools are closed again, some containers stay empty on each page load. That makes the issue very difficult to debug...

  1. Do you have suggestions on how to debug that issue?
  2. Why does Firefox behave differently when DevTools are open?
