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).
