CORS Unblock

No more CORS error by appending 'Access-Control-Allow-Origin: *' header to local and remote web requests when enabled
CORS Unblock is a valuable Edge add-on utilized for bypassing 'XMLHttpRequest' and 'fetch' rejections by altering 'Access-Control-Allow' headers in every outstanding request. It can change default header values, manipulate returned 4xx status codes, permit cross-origin frame embedding, and address CORS policies of redirected URLs. Invocation of the add-on is by pressing the action button or through the right click context menu. It also paves the way for debugging by pretending websites to support unsupported server methods or classes.

Does not work in the slightest. Bummer! Still have to manually disable CORS for dev work, then re-enable it. Anyone have a working plugin?
