ChromeCORS Unblock
By: balvin.perrie
CORS Unblock Chrome extension bypasses CORS errors by appending 'Access-Control-Allow-Origin: *' headers to web requests. Activate with one click!
Features & Capabilities
CORS Unblock is a powerful Chrome extension designed to bypass the common Cross-Origin Resource Sharing (CORS) errors encountered during web development. By appending and modifying headers such as 'Access-Control-Allow-Origin' and 'Access-Control-Allow-Methods', it enables smooth communication between local and remote web requests. Users can activate it easily with a single click and customize which headers to manipulate via the right-click context menu. Beyond basic header modification, the extension offers advanced features: removing Content Security Policy headers to avoid content restrictions, allowing cross-origin frame embedding by removing 'X-Frame-Options', overriding 4xx server responses to simulate support for unsupported methods, and controlling sensitive headers like 'referer' and 'origin' to ensure compatibility with strict servers. It also optionally fixes CORS on redirected URLs and supports SharedArrayBuffer class emulation. This extension is an essential tool for developers tackling cross-origin restrictions effectively.
