How to track a page load progression before events are fired?

more options

I'm working with a third-party project that is loading html, css and javascript into a browser. At some point, a class is added on to an element. With FireFox 70.0.1, is there a way I can walk through the page load progression until that class is added? This way I can see who is adding that element to the page?

If there is an easier way to tell when an event fires in the DOM, that would be awesome. I just want to pin-point which javascript file adds a certain class (injected through javascript), into the DOM.

When working with a project that has over 50 javascript files loaded, it's hard to see "which" js file injects code into the DOM. Can FireFox help me in this case if I know the class name that is being injected?

Many thanks for any assistant.
