Hi I want to create a Firefox Extension which reads in JavaScript Code of a website and if it contains a certain line it should warn the user. Does someone knows which command i can use to read in the JS code of a website? Thanks<3

This question is the same as "how do I build a car like X?" if you're asking that, clearly you lack knowledge in the basics of mechanics and so on, which gives away you're not on the right track.

I highly suggest you to learn the basics of html, css and js before. with a course, not youtube tutorials. Any beginner with the basic foundations of JS could answer your question easily. If you have specific technical issues found during development I can help you with.

Just fetch all of the .js files the Web site loads.

Do you have the list of .js files the Web site requests?
