Restfox CORS Helper от Artelin

Restfox is web based HTTP client (similar to Postman & Insomnia) that allows you to test HTTP endpoints completely in-browser without using a backend or a desktop application.

This extension provides the ability to bypass CORS restrictions so that you can make requests from the Restfox web application without worrying about CORS issues.
