<p>To understand better the behavior of <i>Tor Browser</i>, for example, regarding JavaScript and cookies, you can refer to the <a href="https://2019.www.torproject.org/projects/torbrowser/design/"> <i>Tor Browser</i> design document</a>.</p>
You can change the security level of *Tor Browser* to disable browser features as a trade-off between security and usability.For example, you can set the security level to *Safest* to disable JavaScript completely.
<p>You can safely disregard the message, "Your browser is being managed by your organization," which appears in the <i>Tor Browser</i> preferences.</p>
<p>All this message means is that the automatic updates feature of <i>Tor Browser</i> has been disabled. This is done intentionally in Tails to make sure that no security feature or configuration gets broken by automatic updates of <i>Tor Browser</i>.</p>
