About

🚀 Easily unblock Cross-Origin Resource Sharing (CORS) restrictions with just one click!

Are you tired of seeing CORS errors while accessing APIs, testing web applications, or debugging your projects? The CORS Unblock extension helps you bypass restrictive CORS policies by modifying HTTP response headers, allowing access to restricted resources.

🔹 What This Extension Does:
✅ Removes CORS restrictions on all websites
✅ Automatically adds the Access-Control-Allow-Origin: * header
✅ Works on APIs, JavaScript fetch requests, and browser requests
✅ One-click enable/disable functionality

🔹 Who is This For?

Developers testing APIs and making cross-origin requests
Web Designers embedding content from different origins
Researchers analyzing cross-domain data
Anyone frustrated with CORS errors in Chrome

🔹 How to Use:
1️⃣ Install the extension
2️⃣ Click the CORS Unblock icon in the toolbar
3️⃣ Toggle the extension ON/OFF as needed
4️⃣ Enjoy unrestricted access to APIs and websites

🚧 Important Notes:

This extension only modifies response headers, it does not compromise security.
Some websites may still enforce strict CORS policies server-side.
Disable the extension when not in use to prevent conflicts with other browsing activities.
