Web Scripts Runner

A Chrome extension that lets you save named JavaScript snippets and run them later from reusable action buttons.

What it does

• click the + button in the popup
• give the action a name
• paste a JavaScript console snippet
• save it
• click the saved Run button anytime later on a normal website tab

How execution works now

• uses chrome.userScripts.execute() for user-provided code
• tries MAIN world first for better console-style compatibility
• falls back to USER_SCRIPT world when a site CSP blocks page-context execution
• this avoids the unsafe-eval / new Function(...) error you saw on strict sites

Important Chrome setup

This extension now requires Chrome User Scripts support.

• Chrome 138+: open chrome://extensions, open this extension's Details, and enable Allow User Scripts
• Chrome 135-137: open chrome://extensions and enable Developer mode

Files

• manifest.json - Chrome extension manifest (MV3)
• popup.html / popup.css / popup.js - popup UI
• src/ - storage, execution, and popup controller logic
• tests/ - local automated tests

Load it in Chrome

1. Open chrome://extensions
2. Enable Developer mode
3. Click Load unpacked
4. Select this folder: /Users/oribecher/Projects/chrome-addons/web-scripts-runner
5. If Chrome shows it, also enable Allow User Scripts in the extension details page

Notes

• minimum supported Chrome version is 135
• saved actions are stored with chrome.storage.local
• scripts run on the current active tab
• Chrome still blocks internal pages like chrome:// and the Chrome Web Store
