-      Thunderbird is an email client that allows you to read, write and organise all
-      of your email messages. It is compatible with most email accounts, including the
-      most popular webmail services.
-    </p>
-    <p>
-      Thunderbird is designed by Mozilla, a global community working together to make
-      the Internet better. Mozilla believe that the Internet should be open, public,
-      and accessible to everyone without any restrictions.
-    </p>
-    <ul>
-      <li>Easier than ever to set up a new e-mail account</li>
-      <li>Awesome search allows you to find your messages fast</li>
-      <li>Thousands of add-ons give you the freedom to make Thunderbird your own</li>
