title: Firefox Add-on RESTClient - How to send data-binary file in the request?
body: <p>I am trying to use <a href="http://restclient.net/" rel="nofollow noreferrer">RESTClient</a> Firefox add on to post something equivalent to this:</p>
  
  <pre><code>curl -s -S -X POST -H "Content-type: application/zip" \
    --data-binary @./cluster-config.zip \
    http://${JOINING_HOST}:8001/admin/v1/cluster-config
  </code></pre>
  
  <p>The idea is using this Firefox add-on (RESTClient) to debug my stuff until it works. But I am stuck because I don't find the way to add a file to the request (equivalent to --data-binary parameter of curl)</p>
  
  <p><strong>How can I include a file in the request in RestClient Firefox add-on?</strong></p>
