Mozilla has a nice tool to help identify sources of "slowness and slugishness"[1], you may want to give it a try -- oftentimes it's found that the issue is not Firefox itself, but some extensions, external processes, or undesirable modifications in `about:config`.

- mmis1000 5y agoThat 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.
- gorhill 5y agoIf 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.
- mmis1000 5y agoThis 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.
