Chrome extension: Getting html of page before page renders/loads

Context: I'm making a program that extracts the main content from a webpage. However, currently what I am doing is waiting for the entire webpage to load and render (which can take a long time, especially for pages with a lot of scripts).

What I want is to just get the html of the page right when the page starts loading so I can extract the main content without having to wait for the entire webpage to render and load. 

run_at: "document_start"

in the mainfest.json file does not work because it is run before the html even appears.

Use run_at: "document_start" with DOMContentLoaded event listener (or MutationObserver if you want to process the document while it's loading) in your content script.

You should try "document_end", it should run earlier than the default "document_idle".
