What is Moesif Origin & CORS Changer?
Moesif Origin & CORS Changer is a browser plugin that enables users to send cross-domain requests without Cross Origin Errors. It allows the user to override the Request Origin header and sets Access-Control-Allow-Origin to *. However, its functionality may be limited due to ongoing work from the Chromium team to finalize support for request preflight interception for CORB and CORS. The tool is intended primarily for testing during website development.

Summary

This plugin allows you to send cross-domain requests directly from browser without receiving Cross Origin Errors. You can override the Request Origin header with this plugin and also have Access-Control-Allow-Origin set to *.

Update: We received comments from Chromium team that the support for request preflight interception for CORB thus CORS is still to be finalized. At this point this extension should work for some scenarios but not all, we believe it is still most functional of all CORS extensions out there. We'll keep you updated.

You can override: Request Headers: Origin Response Headers: Access-Control-Allow-Origin, Access-Control-Allow-Methods, Access-Control-Allow-Headers, Access-Control-Allow-Credentials, Access-Control-Expose-Headers

DISCLAIMER: This tool circumvents CORS security rules baked into every browser and is intended for testing your own website during development. Some production websites like Google Docs or Facebook may complain if they detect something that isn't expected. You can use the whitelist feature to only turn on for some domains. To avoid security issues, it is recommend to turn off after debugging.

The domain whitelist works well, but the plugin doesn't support web fonts. For web fonts, it needs Access-Control-Allow-Origin: *
