title: Auto-fill specific login forms
body: <p>Is there any possibility to fill specific login form as Pinterest's one in JavaScript?</p>
  <p>Here's the link - <a href="https://www.pinterest.com/login/" rel="nofollow noreferrer">https://www.pinterest.com/login/</a></p>
  <p>Some hints:</p>
  <blockquote>
  <p>Login field's id is &quot;email&quot;</p>
  <p>Password field's id is &quot;password&quot;</p>
  </blockquote>
  <p>There's no chance to fill it by:</p>
  <pre><code>document.getElementById(&quot;email&quot;).value = &quot;username&quot;;
  document.getElementById(&quot;password&quot;).value = &quot;password&quot;;
  </code></pre>
  <p>because entered data will dissapear after clicking &quot;Login&quot; or clicking into textfields.</p>
