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.
