11) <p>
12) Tor Browser includes a “Security Slider” that lets you
13) increase your security by disabling certain web features that can be
14) used to attack your security and anonymity. Increasing Tor Browser’s
15) security level will stop some web pages from functioning properly, so
16) you should weigh your security needs against the degree of usability
17) you require.
