About

Add Javascript is a powerful, lightweight, and developer-friendly browser extension that allows you to inject custom JavaScript into any domain or specific URL path.

Features:
Toggle with Ease: Quickly enable or disable individual scripts, or use the Global Toggle to turn off all injections at once.
Multiple Code Blocks per Script: Organize your JS code into separate blocks with titles for better readability and maintenance.
Domain or Path Matching: Inject scripts on exact domains (medium.com) or specific paths (medium.com/membership). Subdomains and paths are handled independently.
Search & Filter: Easily find your custom scripts among dozens of entries using the built-in search bar.
Import & Export: Move your custom scripts between different browsers or backup your data with a single click via JSON files.
Privacy Focused: No tracking, no external servers. Your custom scripts are stored locally in your browser.
