+### Preferences
+Set and lock preferences.
+
+**NOTE** On Windows, in order to use this policy, you must clear all settings in the old **Preferences (Deprecated)** section.
+
+Previously you could only set and lock a subset of preferences. Starting with Firefox 81 and Firefox ESR 78.3 you can set many more preferences. You can also set default preferences, user preferences and you can clear preferences.
+
+Preferences that start with the following prefixes are supported:
+```
+accessibility.
+app.update.* (Firefox 86, Firefox 78.8)
+browser.
+datareporting.policy.
+dom.
+extensions.
+general.autoScroll (Firefox 83, Firefox ESR 78.5)
+general.smoothScroll (Firefox 83, Firefox ESR 78.5)
+geo.
+intl.
+layout.
+media.
+network.
+pdfjs. (Firefox 84, Firefox ESR 78.6)
+places.
+print.
+signon. (Firefox 83, Firefox ESR 78.5)
+spellchecker. (Firefox 84, Firefox ESR 78.6)
+ui.
+widget.
+```
+as well as the following security preferences:
+| Preference | Type | Default
+| --- | --- | ---
+| security.default_personal_cert | string | Ask Every Time
+| If set to Select Automatically, Firefox automatically chooses the default personal certificate.
+| security.insecure_connection_text.enabled | bool | false
+| If set to true, adds the words "Not Secure" for insecure sites.
+| security.insecure_connection_text.pbmode.enabled | bool | false
+| If set to true, adds the words "Not Secure" for insecure sites in private browsing.
+| security.insecure_field_warning.contextual.enabled | bool | true
+| If set to false, remove the warning for inscure login fields.
+| security.mixed_content.block_active_content | boolean | true
+| If false, mixed active content (HTTP and HTTPS) is not blocked.
+| security.osclientcerts.autoload | boolean | false
+| If true, client certificates are loaded from the operating system certificate store.
+| security.ssl.errorReporting.enabled | boolean | true
+| If false, SSL errors cannot be sent to Mozilla.
+| security.tls.hello_downgrade_check | boolean | true
+| If false, the TLS 1.3 downgrade check is disabled.
+| security.tls.version.enable-deprecated | boolean | false
+| If true, browser will accept TLS 1.0. and TLS 1.1 (Firefox 86, Firefox 78.8)
+| security.warn_submit_secure_to_insecure | boolean | true
+| If false, no warning is shown when submitting s form from https to http.
+
+
+Using the preference as the key, set the `Value` to the corresponding preference value.
+
+`Status` can be "default", "locked", "user" or "clear"
+
+Default preferences can be modified by the user.
+
+If a value is locked, it is also set as the default.
+
+User preferences persist across invocations of Firefox. It is the equivalent of a user setting the preference. They are most useful when a preference is needed very early in startup so it can't be set as default by policy.
+
+User preferences persist even if the policy is removed, so if you need to remove them, you should use the clear policy.
+
+See the examples below for more detail.
+
+IMPORTANT: Make sure you're only setting a particular preference using this mechanism and not some other way.
