This extension currently provides the following features to Postwoman.

• Overrides CORS restrictions for cross-origin requests.

Building & Experimentation

• Clone the repo
• Run npm install
• Run npm run build to generate the dist folder
• Navigate to about:debugging in Firefox; Select This Firefox in the sidebar
• Click on Load Temporary Add-on... and select the manifest.json in the generated dist folder
• Open https://postwoman.io on Firefox and run queries. It will pass without CORS issues.

NOTE: If you are running Postwoman on a domain which is not https://postwoman.io or https://postwoman.netlify.com/ (for example when running Postwoman on localhost), this extension won't work as a security measure. To make it work, add your domain to manifest.json's matches array within the content_scripts array like so:

 "content_scripts": [
    {
      "matches": [
        "https://mydomainhere.com",
        
        "https://postwoman.io/",
        "https://postwoman.io/*",
        "https://postwoman.netlify.com/*",
        "https://postwoman.netlify.com/"
      ],
      "js": [ "index.js" ]
    }
  ],

Postwoman is built with help of an amazing group of people.
