If you need to add link, you can do this 2 ways.

1. Use variable with the code that you created, but you need to add value to in in the controller.
in the template /storefront/view/default/template/common/header.tp:

<li><a href="<?php echo $account; ?>"><?php echo $text_account; ?></a></li>

in controller /storefront/controller/common/header.php:
Add:

$this->data['text_account'] = $this->language->get('text_account');
$this->data['account'] = $this->html->getURL('account/account');

2. Add relative portion of URL to the template (lazy way )
<li><a href="/index.php?rt=account/account">My Account</a></li>

FYI. For blue menu above, you can add link using admin -> menu without any code changes.

This is in the template file: storefront/view/default/template/common/header.tpl

Look at these lines:

          <li><a href="<?php echo $special; ?>" class="special"><?php echo $text_special; ?></a></li>
          <li class="nav_sep">&nbsp;</li>
          <li><a onclick="bookmark(document.location, '<?php echo addslashes($title); ?>');" class="bookmark"><?php echo $text_bookmark; ?></a></li>
          <li class="nav_sep">&nbsp;</li>
          <li><a href="<?php echo $contact; ?>" class="contact"><?php echo $text_contact; ?></a></li>
          <li class="nav_sep">&nbsp;</li>
          <li><a href="<?php echo $sitemap; ?>" class="sitemap"><?php echo $text_sitemap; ?></a></li>
