<strong>Firefox</strong> has some really strong privacy settings such as <a href="https://support.mozilla.org/kb/enhanced-tracking-protection-firefox-desktop">Enhanced Tracking Protection</a> which can help block various <a href="https://support.mozilla.org/kb/enhanced-tracking-protection-firefox-desktop#w_what-enhanced-tracking-protection-blocks">types of tracking</a>.
These options can be found in the <em>Privacy & Security</em> settings page ( ≡ → Settings → Privacy & Security).

<h4>Extensions</h4>
We normally do not recommend installing any extensions, as they have privileged access within your browser. We make an exception for <a href="/browsers/#additional-resources">uBlock Origin</a>,
a popular content blocker and 🏆️ <a href="https://support.mozilla.org/kb/add-on-badges#w_recommended-extensions">Recommended Extension</a> by Mozilla.
<h4>Arkenfox (advanced)</h4>
The <a href="https://github.com/arkenfox/user.js">Arkenfox project</a> provides a set of carefully considered options for Firefox. These options are quite strict but a few are subjective and can sometimes cause a website to not work properly. You can easily change these settings to suit your needs. We <strong>strongly recommend</strong> reading through the <a href="https://github.com/arkenfox/user.js/wiki">basics</a> section. Arkenfox also enables <a href="https://support.mozilla.org/en-US/kb/containers#w_for-advanced-users">container</a> support.
