-Policies can be specified using the Group Policy templates on Windows (https://github.com/mozilla/policy-templates/tree/master/windows), 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`.

+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.
+| &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.
 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`force_installed`| The extension is automatically installed and can't be removed by the user. This option is not valid for the default configuration and requires an install_url.
 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`normal_installed`| The extension is automatically installed but can be disabled by the user. This option is not valid for the default configuration and requires an install_url.
-| `install_url`| Maps to a URL indicating where Firefox can download a force_installed or normal_installed extension. If installing from the addons.mozilla.org, use the following URL (substituting SHORT_NAME from the URL on AMO), https://addons.mozilla.org/firefox/downloads/latest/SHORT_NAME/latest.xpi. If installing from the local file system, use a file:/// URL. Languages packs are available from https://releases.mozilla.org/pub/firefox/releases/VERSION/PLATFORM/xpi/LANGUAGE.xpi.
-| `install_sources` | Each item in this list is an extension-style match pattern. Users will be able to easily install items from any URL that matches an item in this list. Both the location of the *.xpi file and the page where the download is started from (i.e.  the referrer) must be allowed by these patterns. This setting can be used only for the default configuration.
-| `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", "langpack" 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.
+| `install_url`| Maps to a URL indicating where Firefox can download a force_installed or normal_installed extension. If installing from the addons.mozilla.org, use the following URL (substituting SHORT_NAME from the URL on AMO), https://addons.mozilla.org/firefox/downloads/latest/SHORT_NAME/latest.xpi. If installing from the local file system, use a file:/// URL. Languages packs are available from https://releases.mozilla.org/pub/firefox/releases/VERSION/PLATFORM/xpi/LANGUAGE.xpi. If you need to update the extension, you can change the name of the extension and it will be automatically updated. Extensions installed from file URLs will additional be updated when their internal version changes.
+| `install_sources` | A list of sources from which installing extensions is allowed. **This is unnecessary if you are only allowing the installation of certain extensions by ID.** Each item in this list is an extension-style match pattern. Users will be able to easily install items from any URL that matches an item in this list. Both the location of the *.xpi file and the page where the download is started from (i.e.  the referrer) must be allowed by these patterns. This setting can be used only for the default configuration. If you want to allow the install of extensions from the recommended add-ons page, you must add `about:addons` to this list.
+| `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.
+| `restricted_domains` | An array of domains on which content scripts can't be run. This setting can be used only for the default configuration.

+### Handlers
+Configure default application handlers. This policy is based on the internal format of `handlers.json`.
+
+You can configure handlers based on a mime type (`mimeTypes`), a file's extension (`extensions`), or a protocol (`schemes`).
+
+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.

 ### Preferences
+Set and lock preferences.
+
+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.
+browser.
+datareporting.policy.
+dom.
+extensions.
+geo.
+intl.
+layout.
+media.
+network.
+places.
+print.
+ui.
+widget.
+```
+as well as the following security preferences:
+```
+security.default_personal_cert
+security.insecure_connection_text.enabled
+security.insecure_connection_text.pbmode.enabled
+security.insecure_field_warning.contextual.enabled
+security.mixed_content.block_active_content
+security.osclientcerts.autoload
+security.ssl.errorReporting.enabled
+security.tls.hello_downgrade_check
+security.warn_submit_secure_to_insecure
+```
+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.
