Is your feature request related to a problem? Please describe.

I usually use the Chrome Dev Tools to analyze third party scripts, specifically the longest tasks in the main thread. I analyze the JS of the third-parties and try to identify the performance bottlenecks.

Describe the solution you'd like

I'd like to quickly identify such long tasks, the specific points in the JS script which caused them, and see recommendations how to fix them.

Describe alternatives you've considered

My alternative for the moment is to do it manually, but if I can do it with the help of an LLM, it could save me some time.
