-**IMPORTANT**: This file is in active development along with the policies in Firefox. To get the policy information that corresponds to a specific release, go to https://github.com/mozilla/policy-templates/releases.
+**These policies are in active development and so might contain changes that do not work with current versions of Firefox.**
 
-Policies can either be specified using the Group Policy templates or by creating a file called `policies.json`. On Windows, create a directory called `distribution` where the EXE is located and place the file there. On Mac, the file goes into `Firefox.app/Contents/Resources/distribution`.  On Linux, the file goes into `firefox/distribution`, where `firefox` is the installation directory for firefox, which varies by distribution.
+**You should use the [officially released versions](https://github.com/mozilla/policy-templates/releases) if you are deploying changes.**
 
-The content of the JSON file should look like this:
+Policies can be specified using the [Group Policy templates on Windows](https://github.com/mozilla/policy-templates/tree/master/windows), [Intune on Windows](https://support.mozilla.org/kb/managing-firefox-intune), [configuration profiles on macOS](https://github.com/mozilla/policy-templates/tree/master/mac), or by creating a file called `policies.json`. On Windows, create a directory called `distribution` where the EXE is located and place the file there. On Mac, the file goes into `Firefox.app/Contents/Resources/distribution`.  On Linux, the file goes into `firefox/distribution`, where `firefox` is the installation directory for firefox, which varies by distribution or you can specify system-wide policy by placing the file in `/etc/firefox/policies`.

+Starting with Firefox 65, Firefox 60.5 ESR, a fully qualified path can be used, including UNC paths. You should use the native path style for your operating system. We do not support using %USERPROFILE% or other environment variables on Windows.
+
+If you are specifying the path in the policies.json file on Windows, you need to escape your backslashes (`\\`) which means that for UNC paths, you need to escape both (`\\\\`). If you use group policy, you only need one backslash.
+
+Certificates are installed using the trust string `CT,CT,`.

+### ExtensionSettings
+Manage all aspects of extensions. This policy is based heavily on the [Chrome policy](https://dev.chromium.org/administrators/policy-list-3/extension-settings-full) of the same name.
+
+This policy maps an extension ID to its configuration. With an extension ID, the configuration will be applied to the specified extension only. A default configuration can be set for the special ID "*", which will apply to all extensions that don't have a custom configuration set in this policy.
+
+To obtain an extension ID, install the extension and go to about:support. You will see the ID in the Extensions section. I've also created an extension that makes it easy to find the ID of extensions on AMO. You can download it [here](https://github.com/mkaply/queryamoid/releases/tag/v0.1).
+
+The configuration for each extension is another dictionary that can contain the fields documented below.
+
+| Name | Description |
+| --- | --- |
+| `installation_mode` | Maps to a string indicating the installation mode for the extension. The valid strings are `allowed`,`blocked`,`force_installed`, and `normal_installed`.
+| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`allowed` | Allows the extension to be installed by the user. This is the default behavior. There is no need for an install_url; it will automatically be allowed based on the ID.
+| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`blocked`| Blocks installation of the extension and removes it from the device if already installed.

+| `allowed_types` | This setting whitelists the allowed types of extension/apps that can be installed in Firefox. The value is a list of strings, each of which should be one of the following: "extension", "theme", "dictionary", "locale" This setting can be used only for the default configuration.
+| `blocked_install_message` | This maps to a string specifying the error message to display to users if they're blocked from installing an extension. This setting allows you to append text to the generic error message displayed when the extension is blocked. This could be be used to direct users to your help desk, explain why a particular extension is blocked, or something else. This setting can be used only for the default configuration.

+
+Within each handler type, you specify the given mimeType/extension/scheme as a key and use the following subkeys to describe how it is handled.
+
+| Name | Description |
+| --- | --- |
+| `action`| Can be either `saveToDisk`, `useHelperApp`, `useSystemDefault`.
+| `ask` | If `true`, the user is asked if what they want to do with the file. If `false`, the action is taken without user intervention.
+| `handlers` | An array of handlers with the first one being the default. If you don't want to have a default handler, use an empty object for the first handler. Choose between path or uriTemplate.
+| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`name` | The display name of the handler (might not be used).
+| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`path`| The native path to the executable to be used.
+| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`uriTemplate`| A url to a web based application handler. The URL must be https and contain a %s to be used for substitution.

+
+`Allow` is a list of origins where the feature is allowed.
+
+`Block` is a list of origins where the feature is not allowed.
+
+`BlockNewRequests` determines whether or not new requests can be made for the feature.
+
+`Locked` prevents the user from changing preferences for the feature.

+### 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
+| &nbsp;&nbsp;&nbsp;&nbsp;If set to Select Automatically, Firefox automatically chooses the default personal certificate.
+| security.insecure_connection_text.enabled | bool | false
+| &nbsp;&nbsp;&nbsp;&nbsp;If set to true, adds the words "Not Secure" for insecure sites.
+| security.insecure_connection_text.pbmode.enabled | bool | false
+| &nbsp;&nbsp;&nbsp;&nbsp;If set to true, adds the words "Not Secure" for insecure sites in private browsing.
+| security.insecure_field_warning.contextual.enabled | bool | true
+| &nbsp;&nbsp;&nbsp;&nbsp;If set to false, remove the warning for inscure login fields.
+| security.mixed_content.block_active_content | boolean | true
+| &nbsp;&nbsp;&nbsp;&nbsp;If false, mixed active content (HTTP and HTTPS) is not blocked.
+| security.osclientcerts.autoload | boolean | false
+| &nbsp;&nbsp;&nbsp;&nbsp;If true, client certificates are loaded from the operating system certificate store.
+| security.ssl.errorReporting.enabled | boolean | true
+| &nbsp;&nbsp;&nbsp;&nbsp;If false, SSL errors cannot be sent to Mozilla.
+| security.tls.hello_downgrade_check | boolean | true
+| &nbsp;&nbsp;&nbsp;&nbsp;If false, the TLS 1.3 downgrade check is disabled.
+| security.tls.version.enable-deprecated | boolean | false
+| &nbsp;&nbsp;&nbsp;&nbsp;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
+| &nbsp;&nbsp;&nbsp;&nbsp;If false, no warning is shown when submitting s form from https to http.
+&nbsp;
+
+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.
