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