Privoxy may be invoked with the following command line options:
Before changing to the user ID given in the --user option,
chroot to that user's home directory, i.e. make the kernel
pretend to the Privoxy process that the directory tree starts
there. If set up carefully, this can limit the impact of
possible vulnerabilities in Privoxy to the files contained in
Exit after loading the configuration files before binding to the
listen address. The exit code signals whether or not the
configuration files have been successfully loaded.
If the exit code is 1, at least one of the configuration files
is invalid, if it is 0, all the configuration files have been
successfully loaded (but may still contain errors that can
currently only be detected at run time).
This option doesn't affect the log setting, combination with
"--no-daemon" is recommended if a configured log file shouldn't
--help Print brief usage info and exit.
Don't become a daemon, i.e. don't fork and become process
group leader, don't detach from controlling tty, and do all
On startup, write the process ID to pidfile. Delete the pidfile
on exit. Failure to create or delete the pidfile is non-fatal.
If no --pidfile option is given, no PID file will be used.
Initialize the resolver library using hostname before
chroot'ing. On some systems this reduces the number of files
that must be copied into the chroot tree.
After (optionally) writing the PID file, assume the user ID of
user and the GID of group, or, if the optional group was not
given, the default group of user. Exit if the privileges are not
individual needs and tastes. It has application for both stand-alone
systems and multi-user networks.

INSTALLATION AND USAGE
Browsers can either be individually configured to use Privoxy as a HTTP
proxy (recommended), or Privoxy can be combined with a packet filter to
build an intercepting proxy (see config). The default setting is for
localhost, on port 8118 (configurable in the main config file). To
set the HTTP proxy in Firefox, go through: Tools; Options; General;
Connection Settings; Manual Proxy Configuration.
For Internet Explorer, go through: Tools; Internet Properties;
Connections; LAN Settings.
The Secure (SSL) Proxy should also be set to the same values, otherwise
https: URLs will not be proxied. Note: Privoxy can only proxy HTTP and
HTTPS traffic. Do not try it with FTP or other protocols. HTTPS
presents some limitations, and not all features will work with HTTPS
For other browsers, check the documentation.
Privoxy can be configured with the various configuration files. The
default configuration files are: config, default.filter, default.action
and default.action. user.action should be used for locally defined
exceptions to the default rules in match-all.action and default.action,
and user.filter for locally defined filters. These are well commented.
On Unix and Unix-like systems, these are located in /etc/privoxy/ by
Privoxy uses the concept of actions in order to manipulate the data
stream between the browser and remote sites. There are various actions
available with specific functions for such things as blocking web
sites, managing cookies, etc. These actions can be invoked individually
or combined, and used against individual URLs, or groups of URLs that
can be defined using wildcards and regular expressions. The result is
that the user has greatly enhanced control and freedom.
The actions list (ad blocks, etc) can also be configured with your web
browser at http://config.privoxy.org/ (assuming the configuration
Various other files should be included, but may vary depending on
platform and build configuration. Additional documentation should be
included in the local documentation directory.
Privoxy terminates on the SIGINT and SIGTERM signals. Log rotation
scripts may cause a re-opening of the logfile by sending a SIGHUP to
Privoxy. Note that unlike other daemons, Privoxy does not need to be
made aware of config file changes by SIGHUP -- it will detect them
automatically. Signals other than the ones listed above aren't
explicitly handled and result in the default action defined by the
