Automatic testing of Firefox browser configurations. How to make Firefox great again?

Question

Automation

I have been using Firefox for many years primarily because of the sheer number of extensions that make my life so much easier. There is only one problem. Now I have 100500 extensions (add-ones) installed and with the naked eye you can see that the launch speed, page opening time and stability are deteriorating noticeably. Periodically, I manually disable extensions one at a time or in batches and in this way I can find one or two black sheep of the extension that ruin everything. I do not have unnecessary extensions - I use everything. I don't use ad blockers.
The question is - how can you organize automatic testing? That is, we turn on one extension - we launch the browser, measure the launch time and page load time, then turn on the next one, etc.
