Show HN: I'm Building a Browser for Reverse Engineers

I have a project (in my rather long project backlog) that involves hooking JS APIs to download youtube videos. I'm worried that if my extension (or a similar extension) gained enough popularity, youtube would start inspecting the relevant JS objects to see if they'd been replaced with proxy instances.

Aside from playing a hooking/patching game of cat and mouse, I don't think this is fully solvable without modifying the browser engine itself - then you can hook things in a way that's completely transparent to the JS in webpages.

Was just about to comment this I’ve played that exact cat and mouse game before there’s also another fun way to hook I used to like by doing something like Object.defineProperty on Object.prototype to globally hook onto something and you can do lots of stuff with that it’s pretty useful in user scripts
