How to download a site page with a hierarchy of folders specified in the header and in the tags?

Question

Parsing

faced such a problem that various wget and teleport pro do not work because the site is under the roof of cloudware and the window that authenticates the browser appears first.

It remains only to enter the site through the existing browser and save the page, but in this case all paths are ignored. but I would like to have assets separately in it neatly css, js img, etc.

But it doesn't work with chrome or firefox.

What else can help us?
