If you have ever stared at a empty screen, a numb DOM, or a console full of race conditions even though building browser go to-ons, you know the sting. These tools affect in a strange gray zone. They inject scripts into a heavily obfuscated, hastily shifting web application, hear to network requests, scrape DOM elements upon the fly, and decrypt cached media payloads back the user even realizes a page has loaded.
