How to automatically load html page code when opened in browser?

Question

Google Chrome

Maybe someone knows an add-on for automatically downloading the html code of a page after opening.
You need to download even when the page is opened in the background.

PS I go to some site. I find the necessary link in it, click open in a new window, and the html code is automatically downloaded for the open tab, and not manually through save as ...

PSS Or maybe there is an add-on that downloads all the opening of the tab into a folder in the form of html code pages.
