Overview
Typically, you can execute custom JavaScript code in the browser's DevTools > Console.
This extension implements functionality missing from browsers, to save custom JavaScript code that can:
* Automatically execute when the page loads.
* Manually execute with a button click.
This extension also supports CSS code, which is internally converted to JavaScript code for execution.
This extension is not a replacement for Greasemonkey, so it doesn't support Greasemonkey-specific code.
