+ <p>The upgrade process to Mac OS X Mavericks (10.9) from an earlier
+ version of OS X deletes all user accounts that are either not part of
+ OS X itself or are not interactive user accounts (ones you log in
+ with). Since, for the sake of security, <span class=
+ "APPLICATION">Privoxy</span> runs as a non-privileged user that is
+ created by its installer (_privoxy), it can no longer start up once
+ that account gets deleted. The solution is to perform a complete

+ "APPLICATION">uninstall.command</span> script (either back up your
+ configuration files or select to not have the uninstaller remove them
+ when it prompts you) and then reinstall <span class=

+ What are tainted sockets and how do I prevent them?</a></h3>
+
+ <p><span class="APPLICATION">Privoxy</span> marks sockets as tainted
+ when it can't use them to serve additional requests. This does not
+ necessarily mean that something went wrong and information about
+ tainted sockets is only logged if connection debugging is enabled
+ (debug 2).</p>
+
+ <p>For example server sockets that were used for CONNECT requests
+ (which are used to tunnel https:// requests) are considered tainted
+ once the client closed its connection to <span class=
+ "APPLICATION">Privoxy</span>. Technically <span class=
+ "APPLICATION">Privoxy</span> could keep the connection to the server
+ open, but the server would not accept requests that do not belong to
+ the previous TLS/SSL session (and the client may even have terminated
+ the session).</p>
+
+ <p>Server sockets are also marked tainted when a client requests a
+ resource, but closes the connection before <span class=
+ "APPLICATION">Privoxy</span> has completely received (and forwarded)
+ the resource to the client. In this case the server would (probably)
+ accept additional requests, but <span class=
+ "APPLICATION">Privoxy</span> could not get the response without
+ completely reading the leftovers from the previous response.</p>
+
+ <p>These are just two examples, there are currently a bit more than 25
+ scenarios in which a socket is considered tainted.</p>
+
+ <p>While sockets can also be marked tainted as a result of a technical
+ problem that may be worth fixing, the problem will be explicitly logged
+ as error.</p>
