Saving the current state of a browser-rendered page

Question

HTML

Is it possible to save the current state of the rendered page as static HTML with links to images, CSS (calculated if possible) using an extension or a bookmarklet?

Let's say I visit a website. The page has been rendered, all scripts have been processed, elements have been added to the DOM, and so on. Those. on the screen I see the current state. I can "play with fonts", but how do I save the result for later review and editing? Preferably with one button.

Answer 1

The simplest script for GreaseMonkey.
If viewing is planned over the network, push the source to some pastebin.

Answer 2

OK, thanks. Hopefully someone besides me will still use it.
