Key Features:

• Precise Domain Control
- Grant specific websites permission to access external APIs
- Manage permissions on a per-domain basis
- Revoke access anytime through an intuitive interface

• Security-First Design
- No user data collection
- All operations performed locally in your browser

- Programmatic permission requests
- Seamless cross-origin requests once authorized

• Lightweight & Efficient

For Developers:
CORS Unblock provides a straightforward API to request domain access permissions. Once user authorization is granted, your web application can make cross-origin requests without complex proxy servers or CORS configurations.

For Users:
The extension works automatically in the background. When a web application needs cross-origin access, you'll receive a clear permission request. You maintain full control over which domains can communicate with each other.

Privacy & Security:
We take your privacy seriously. CORS Unblock:
- Collects no user data
- Processes all operations locally
- Requires explicit permission for each domain
- Allows instant permission revocation

This extension is perfect for developers building modern web applications and users who want to safely enable cross-origin capabilities while maintaining control over their browsing security.
