That is indeed a powerful tool that gives you the god view of everything what could happened.(Which normal web devtools definitely can't) However, it is also sometimes really hard to interpret the results. There are so many data there, some of them comes from Firefox internal, some of them comes from 3rd extension. Something in different thread actually chains together, but the ui does not show. I think it need some improvements to help the user reading the results.

If you suspect the issue is with Firefox, you can open an issue with the profiling data attached, Firefox devs know how to interpret the data.
This is also way it is powerful. It used to be impossible for Mozilla to inspect the bug if they can't reproduce it themselves and consistently. But with the new profiler, you can screenshot the moments it bugs out either on reporter's computer or dev's. Makes the bug you used to be impossible to debug possible to debug.
