Determine which script is slowing the page down in Firefox
A page is very slow and laggy in Firefox. I am certain it's one of the many Javascripts slowing it down.

Out of curiosity, I'd like to figure out which script is creating the heaviest load. Note that I also have some blocked with uBlock origin, and I don't want to unblock those - I want to see which of the scripts *currently not blocked* is slowing it down.

Surely there's a way to use the inspector to get such a basic performance stat. How do I that? All I care about is which script is responsible for what % of computational demand, it doesn't need any more detail beyond that.
