Referrer logging

Turn referrer logging off if you do not want one site to know which other site you just came from.

Note: Some sites depend on referrer logging to work.

Automatic redirection

Disable automatic redirection if you would rather click redirection links manually.

To make sure all pages navigated to within the site are also deleted, check the option to use cookies to trace password protected pages.
