-### 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)

-### 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/.
