title: Adding Headers to Firefox HTTP Request without Using PlugIns
body: <p>I have Firefox version 52.1. I cannot udpate to newer version, nor can I add plugins that people ordinarily install to address these issues. </p>
  
  <p>I am calling some rest services that require communicating that these are POST request plus a couple of other things ordinarily communicated through hearder information.</p>
  
  <p>What options do I have for adding these specific header requirements to my Firefox request assuming I cannot add plugins or upgrade to a newer version of the browser? Thank you.</p>
