Extension summary

This extension is meant to be used by web developers who need to test UI changes from their local machines against a remote API that doesn't allow localhost CORS requests.

Make sure you understand how CORS works (https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS) before enabling this extension. As a best practice, you should lock down the intercepted URL pattern to only the API you are actually trying to test.
