CORS dev tool - Lightweight web development tool

CORS dev tool is a lightweight Firefox add-on that allows developers to modify Ajax responses and configure Cross-Origin Resource Sharing (CORS) headers. It enables users to customize Access-Control-Allow-Origin, Access-Control-Expose-Headers, Access-Control-Max-Age, Access-Control-Allow-Credentials, Access-Control-Allow-Methods, and Access-Control-Allow-Headers headers to grant access to specified resources from different source servers.

Add-on summary

Users can set different return values to allow users to be granted access to specified resources from different source servers. Users can customize the value of the HTTP response header -Access-Control-Allow-Origin specifies either a single origin, which tells browsers to allow that origin to access the resource; -Access-Control-Expose-Headers header lets a server whitelist headers that browsers are allowed to access. -Access-Control-Max-Age header indicates how long the results of a preflight request can be cached. -Access-Control-Allow-Credentials header Indicates whether or not the response to the request can be exposed when the credentials flag is true. -Access-Control-Allow-Methods header specifies the method or methods allowed when accessing the resource. This is used in response to a preflight request.

  • Access-Control-Allow-Headers header is used in response to a preflight request to indicate which HTTP headers can be used when making the actual request.

It should be noted that when Access-Control-Allow-Origin is set to "*", the identity certificate cannot be attached. Of course you can specify a unique Origin such as http://localhost:3000

Instructions After installing the plugin, click the icon in the upper right corner to enable "cross-source resource sharing".
