I often see a demo for some library or other, and I want to try to make a small change. So I have to download the entire page with all dependencies and then make the change there. I'd like to be able to make the change when I view the source code in the browser.

    The built-in developer tools allow you to modify things, can I post that as an answer? If it is not a good solution, please edit your question to explain why, thanks :-) – Nicolas Raoul Jan 10 '19 at 13:57

Try tampermonkey. This extension changes the HTML code of the page with Javascript, when the page loads. This is called DOM manipulation.

Tampermonkey is not really a High-Level HTML editor, though.

For instance this script: https://greasyfork.org/en/scripts/536-imdb-standard-deviation/code

changes this: Arithmetic mean = 7.5 Median = 8

to this: Arithmetic mean = 7.5 Median = 8 Standard Deviation = 2.02

on the IMDB Ratings page of 'Black Mirror' movie
