title: Firefox won't redirect to HTTPS properly
body: <p>I've wrote the lines below in the .htaccess of my wordpress website, however, Firefox redirects neither <a href="http://mywebsite.com" rel="nofollow noreferrer">http://mywebsite.com</a> nor <a href="http://www.mywebsite.com" rel="nofollow noreferrer">http://www.mywebsite.com</a> to <a href="https://www.mywebsite.com" rel="nofollow noreferrer">https://www.mywebsite.com</a>. All the other browsers redirects properly.</p>
  
  <pre><code># BEGIN WordPress
  &lt;IfModule mod_rewrite.c&gt;
  RewriteEngine On
  RewriteBase /
  
  RewriteCond %{HTTPS} !=on
  RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
  
  RewriteRule ^index\.php$ - [L]
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule . /index.php [L]
  &lt;/IfModule&gt;
  
  # END WordPress
  </code></pre>
  
  <p>Does anyone know what's the issue?</p>
