+<h3 id="redirection-issues-http-referer">Redirection issues (HTTP Referer)</h3>
+<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>
+<p>See:</p>
+<ul>
+<li><a href="https://en.wikipedia.org/wiki/HTTP_referer">HTTP referer</a> (Wikipedia)<a href=".html"></a></li>

+<h3 id="firefox-http-referer-options">Firefox HTTP Referer options</h3>
+<p>HTTP settings are available by browsing <code>about:config</code>, here are the available settings and their values.</p>
+<p><code>network.http.sendRefererHeader</code> - determines when to send the Referer HTTP header</p>
+<ul>
+<li>0: Never send the referring URL
+<ul>
+<li>not recommended, may break some sites</li>
+</ul></li>
+<li>1: Send only on clicked links</li>
+<li>2 (default): Send for links and images</li>
+</ul>
+<p><code>network.http.referer.XOriginPolicy</code> - Cross-domain origin policy</p>
+<ul>
+<li>0 (default): Always send</li>
+<li>1: Send if base domains match</li>
+<li>2: Send if hosts match</li>
+</ul>
+<p><code>network.http.referer.spoofSource</code> - Referer spoofing (~faking)</p>
+<ul>
+<li>false (default): real referer</li>
+<li>true: spoof referer (use target URI as referer)</li>
+</ul>
+<p><code>network.http.referer.trimmingPolicy</code> - trim the URI not to send a full Referer</p>
+<ul>

+<li>2: scheme+host+port</li>

+<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>

 #Troubleshooting
+## Browser
+### Redirection issues (HTTP Referer)
+Depending on its configuration and installed plugins, the browser may remove or alter (spoof) HTTP referers, thus preventing Shaarli from properly redirecting between pages.
+
+See:
+- [HTTP referer](https://en.wikipedia.org/wiki/HTTP_referer) (Wikipedia)[](.html)
+- [Improve online privacy by controlling referrer information](http://www.ghacks.net/2015/01/22/improve-online-privacy-by-controlling-referrer-information/)[](.html)
+- [Better security, privacy and anonymity in Firefox](http://b.agilob.net/better-security-privacy-and-anonymity-in-firefox/)[](.html)
+
+### Firefox HTTP Referer options
+HTTP settings are available by browsing `about:config`, here are the available settings and their values.
+
+`network.http.sendRefererHeader` - determines when to send the Referer HTTP header
+- 0: Never send the referring URL
+    - not recommended, may break some sites
+- 1: Send only on clicked links
+- 2 (default): Send for links and images
+
+`network.http.referer.XOriginPolicy` - Cross-domain origin policy
+- 0 (default): Always send
+- 1: Send if base domains match
+- 2: Send if hosts match
+
+`network.http.referer.spoofSource` - Referer spoofing (~faking)
+- false (default): real referer
+- true: spoof referer (use target URI as referer)
+
+`network.http.referer.trimmingPolicy` - trim the URI not to send a full Referer
+- 0 (default): send full URI
+- 1: scheme+host+port+path
+- 2: scheme+host+port
+
+### Firefox, localhost and redirections
+`localhost` 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.
+
+To solve this, assign a local domain to your host, e.g.
+```
+127.0.0.1 localhost desktop localhost.lan
+::1       localhost desktop localhost.lan
+```
+
+and browse Shaarli at http://localhost.lan/.

 Follow the instructions in the error message. Make sure you are accessing shaarli via a direct IP address or a proper hostname. If you have **no dots** in the hostname (e.g. `localhost` or `http://my-webserver/shaarli/`), some browsers will not store cookies at all (this respects the [HTTP cookie specification](http://curl.haxx.se/rfc/cookie_spec.html)).[](.html)
