title: How to prevent Thunderbird from rewriting URLs to hyperlinks when composing html emails?
body: <p>I'm using Thunderbird 52.5.2 on Windows 7.</p>
  
  <p>When I compose the html emails and send, Thunderbird will convert the email addresses and the http:// urls I wrote to clickable hyperlinks when sending the email out. I don't want Thunderbird to do that for me and I would do that manually when I need by insert->links.</p>
  
  <p>How to prevent Thunderbird from automatically rewriting URLs to hyperlinks when I compose and send the html emails ?</p>
  
  <p>For example, I would like to compose a html email like this:</p>
  
  <p><a href="https://i.stack.imgur.com/e7mJC.png" rel="nofollow noreferrer">Email content I composed (I'm not able to embed img now, please click to view)</a></p>
  
  <p>Thunderbird will rewrite the email address and http url as below (source code view)</p>
  
  <pre><code>&lt;html&gt;
    &lt;head&gt;
  
      &lt;meta http-equiv="content-type" content="text/html; charset=en-US"&gt;
    &lt;/head&gt;
    &lt;body text="#000000" bgcolor="#FFFFFF"&gt;
      &lt;b&gt;H&lt;/b&gt;&lt;i&gt;ELLO&lt;/i&gt;&lt;br&gt;
      This is an email address &lt;a class="moz-txt-link-abbreviated" href="mailto:dummy@example.com"&gt;dummy@example.com&lt;/a&gt;&lt;br&gt;
      This is a http url &lt;a class="moz-txt-link-freetext" href="http://www.example.com/dummy.html"&gt;http://www.example.com/dummy.html&lt;/a&gt;&lt;br&gt;
      &lt;br&gt;
    &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>But I want Thunderbird keep what I wrote as below (source code view):</p>
  
  <pre><code>&lt;html&gt;
    &lt;head&gt;
  
      &lt;meta http-equiv="content-type" content="text/html; charset=en-US"&gt;
    &lt;/head&gt;
    &lt;body text="#000000" bgcolor="#FFFFFF"&gt;
      &lt;b&gt;H&lt;/b&gt;&lt;i&gt;ELLO&lt;/i&gt;&lt;br&gt;
      This is an email address dummy@example.com&lt;br&gt;
      This is a http url http://www.example.com/dummy.html&lt;br&gt;
      &lt;br&gt;
    &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
