@SuperDicq @privateger The problem is that JavaScript engines are not designed to allow for that kind of thing - they love running any and all JavaScript on a webpage and extensions can only stop some of it from executing.

The closest thing there is to that is Haketilo; https://haketilo.koszko.org/ but the browser extension that allows usage with javascript.enabled=false is depreciated but no-one really bothers to write Haketilo packages, as the sort who would care to do so just make their website function in the superior way (without JavaScript).
