The type of development I mean is GreaseMonkey or TamperMonkey scripts -- or even browser plugins -- that modify and "hack" web pages after they've loaded in the browser.<p>Is there a name to refer to this type of thing? Is this an accepted or pseudo-discipline? I'm trying to find best practices around this, but it's hard when there doesn't seem to be a nomenclature around it.
User scripts is the name you're looking for.<p><a href="https://github.com/awesome-scripts/awesome-userscripts?tab=readme-ov-file">https://github.com/awesome-scripts/awesome-userscripts?tab=r...</a>
