 # 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.

-### 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)
-    - known to break some functionality in Shaarli
-
-`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 only 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/.

 - You may be using OperaTurbo or OperaMini, which use their own proxies which may change from time to time.
 - If you have another application on the same webserver where Shaarli is installed, these application may forcefully expire php sessions.

 ## Sessions do not seem to work correctly on your server
 
 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)).
