Overview
Product summary
Review the store description, core capabilities, and common use cases.
Allow CORS: Access-Control-Allow-Origin lets you easily perform cross-domain Ajax requests in web applications.
Simply activate the add-on and perform the request. CORS or Cross-Origin Resource Sharing is blocked in modern browsers by default (in JavaScript APIs). Installing this add-on will allow you to unblock this feature. Please note that, when the add-on is added to your browser, it is inactive by default (toolbar icon is grey C letter). If you want to activate the add-on, please open the toolbar popup and press the toggle button on the left side. The icon will turn to an orange C letter.
If you have a feature request or found a bug to report, please fill out the bug report form on the add-on's homepage (https://mybrowseraddon.com/access-control-allow-origin.html).

works well with requests without preflight request (options). Unfortunately doesn't change the things for preflight request

You should have whitelist for domains where you want this feature to enabled, not other way around...
