Explore how to create and run custom userscripts with FXVNPRo Script Manager

FXVNPRo Script Manager is a secure Chrome extension that allows users to create, edit, and run custom JavaScript userscripts on any website. It is designed for privacy-focused users who want complete control over what scripts run and where they run.​

Getting Started
Install the Extension
Add FXVNPRo Script Manager from the Chrome Web Store.

Create a New Script

Open the extension popup.

Click “New Script.”

Enter your custom JavaScript code.

Optionally specify which domains (via hostnames or regex) should auto‑run the script.

Run a Script Manually
Use the “Run Now” button to inject and run your script on the currently active tab. This action requires an explicit click each time.

Manage Permissions
The extension uses optional host permissions, meaning it will only request access to sites where you enable automatic execution.
This avoids unnecessary blanket permissions and enhances privacy.

Import/Export Scripts
You can back up or transfer your userscripts as JSON files. This makes it easy to share or restore your custom setups.

Privacy and Security
All scripts and settings are stored locally in your browser.

No data, page content, or browsing history is transmitted externally.

Optional telemetry is disabled by default, and if turned on, it only sends minimal anonymous events like “popup_open” or extension version.

Ideal Use Cases
FXVNPRo Script Manager is useful for:

Automating repetitive tasks on specific trading or research sites.

Customizing the UI of frequently visited platforms.

Injecting helper tools or analytics into websites you manage.
