title: Firefox Quantum REST client?
body: <p>Pre-version 57 of Firefox had many wonderful add-ons for REST API testing. These REST clients no longer work with Firefox Quantum. While I found some simple, pre 1.0 add-ons in Quantum (<a href="https://addons.mozilla.org/en-US/firefox/addon/rested/" rel="nofollow noreferrer">click here for example</a>), my hunch is that there must be something more robust that is on par with the pre-57 version add-ons. Or perhaps even BUILT-IN to Firefox Quantum Developer? I would like for someone to answer this post with current options for REST Clients in Firefox Quantum Developer - either built-in, or, as an add-on - that will bring me up to speed and have the same robust qualities of the pre-57 versions. </p>
  
  <p>For example I used to use these two, now not supported:</p>
  
  <ol>
  <li>RESTEasy (<a href="https://addons.mozilla.org/en-US/firefox/addon/rest-easy/" rel="nofollow noreferrer">click here</a>) </li>
  <li>RESTClient (<a href="http://restclient.net/" rel="nofollow noreferrer">click here</a>)</li>
  </ol>
  
  <p>One one think that googling "Firefox Quantum Developer Rest Client How to" would result in something that would answer my question. If you do try this make sure to switch from Any Time to "previous year" - this will filter out many pre-57 search results. What will find is only one listed: (<a href="https://addons.mozilla.org/en-US/firefox/addon/rested/" rel="nofollow noreferrer">click here</a>) - which I am sure you will agree with me that is barely a pre-release and needs more time to mature before being production ready.</p>
  
  <p>So what is going on here? Does Firefox Quantum has a REST Client integrated and I simply cannot find it? What are the professionals using for their REST Client needs with Firefox Quantum? etc.</p>
