About Scripts Injector

Scripts Injector is a high-performance, Manifest V3 Chrome extension engineered to inject custom JavaScript and CSS payloads into targeted web pages based on sophisticated URL glob patterns. Operating at the browser's background service worker level, the mechanism bypasses isolated extension environments, executing scripts directly within the target site's `MAIN` execution world while seamlessly handling Trusted Types enforcement. Designed for both developers and power users, it provides a robust platform for real-time web modification and scripting orchestration.
