+<p>Depending on its configuration and installed plugins, the browser may remove or alter (spoof) HTTP referers, thus preventing Shaarli from properly redirecting between pages.</p>

+<h3 id="firefox-localhost-and-redirections">Firefox, localhost and redirections</h3>
+<p><code>localhost</code> is not a proper Fully Qualified Domain Name (FQDN); if Firefox has been set up to spoof referers, or anly accept requests from the same base domain/host, Shaarli redirections will not work properly.</p>
+<p>To solve this, assign a local domain to your host, e.g.</p>
+<pre><code>127.0.0.1 localhost desktop localhost.lan
+::1       localhost desktop localhost.lan</code></pre>
+<p>and browse Shaarli at <a href="http://localhost.lan/" class="uri">http://localhost.lan/</a>.</p>
