Web Injector

Inject JavaScript code into every page (e.g. to help with debugging). For example, make your own wrapper for console logging.

Web Injector injects whatever custom JavaScript code you want into every web page. You can write an advanced wrapper for console logging; include utility functions for debugging; hide elements by class or id; or any other creative thing you can think of. I hope you enjoy this extension, and if you have ideas for improvement, please share!

Simple and rather easy to work with but unfortunately it has a bug that prevents the script from being saved. Sometimes the script does not save but it does when you click the beautify button.
