1 **These policies are in active development and so might contain changes that do not work with current versions of Firefox.**
3 **You should use the [officially released versions](https://github.com/mozilla/policy-templates/releases) if you are deploying changes.**
5 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`.

623 ### Certificates | Install
625 Install certificates into the Firefox certificate store. If only a filename is specified, Firefox searches for the file in the following locations:
628 - %USERPROFILE%\AppData\Local\Mozilla\Certificates
629 - %USERPROFILE%\AppData\Roaming\Mozilla\Certificates
631 - /Library/Application Support/Mozilla/Certificates
632 - ~/Library/Application Support/Mozilla/Certificates
634 - /usr/lib/mozilla/certificates
635 - /usr/lib64/mozilla/certificates
636 - ~/.mozilla/certificates
638 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.
640 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.
642 Certificates are installed using the trust string `CT,CT,`.
644 Binary (DER) and ASCII (PEM) certificates are both supported.

2012 ### EnableTrackingProtection
2013 Configure tracking protection.
2015 If this policy is not configured, tracking protection is not enabled by default in the browser, but it is enabled by default in private browsing and the user can change it.
2017 If `Value` is set to false, tracking protection is disabled and locked in both the regular browser and private browsing.
2019 If `Value` is set to true, tracking protection is enabled by default in both the regular browser and private browsing and the `Locked` value determines whether or not a user can change it.
2021 If `Cryptomining` is set to true, cryptomining scripts on websites are blocked.
2023 If `Fingerprinting` is set to true, fingerprinting scripts on websites are blocked.
2025 `Exceptions` are origins for which tracking protection is not enabled.

2176 Control the installation, uninstallation and locking of extensions.
2178 While this policy is not technically deprecated, it is recommended that you use the **[`ExtensionSettings`](#extensionsettings)** policy. It has the same functionality and adds more. It does not support native paths, though, so you'll have to use file:/// URLs.
2180 `Install` is a list of URLs or native paths for extensions to be installed.
2182 `Uninstall` is a list of extension IDs that should be uninstalled if found.
2184 `Locked` is a list of extension IDs that the user cannot disable or uninstall.

2258 ### ExtensionSettings
2259 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.
2261 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.
2263 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).
2265 The configuration for each extension is another dictionary that can contain the fields documented below.
2267 | Name | Description |
2269 | `installation_mode` | Maps to a string indicating the installation mode for the extension. The valid strings are `allowed`,`blocked`,`force_installed`, and `normal_installed`.
2270 | `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.
2271 | `blocked`| Blocks installation of the extension and removes it from the device if already installed.
2272 | `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.
2273 | `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.
2274 | `install_url`| Maps to a URL indicating where Firefox can download a force_installed or normal_installed extension. If installing from the local file system, use a [```file:///``` URL](https://en.wikipedia.org/wiki/File_URI_scheme). 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. 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.
2275 | `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.
2276 | `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.
2277 | `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.
2278 | `restricted_domains` | An array of domains on which content scripts can't be run. This setting can be used only for the default configuration.

2508 You can configure handlers based on a mime type (`mimeTypes`), a file's extension (`extensions`), or a protocol (`schemes`).
2510 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.
2512 | Name | Description |
2514 | `action`| Can be either `saveToDisk`, `useHelperApp`, `useSystemDefault`.
2515 | `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.
2516 | `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.
2517 | `name` | The display name of the handler (might not be used).
2518 | `path`| The native path to the executable to be used.
2519 | `uriTemplate`| A url to a web based application handler. The URL must be https and contain a %s to be used for substitution.

3166 ### ManualAppUpdateOnly
3168 Switch to manual updates only.
3170 If this policy is enabled:
3171 1. The user will never be prompted to install updates
3172 2. Firefox will not check for updates in the background, though it will check automatically when an update UI is displayed (such as the one in the About dialog). This check will be used to show "Update to version X" in the UI, but will not automatically download the update or prompt the user to update in any other way.
3173 3. The update UI will work as expected, unlike when using DisableAppUpdate.
3175 This policy is primarily intended for advanced end users, not for enterprises.
3177 **Compatibility:** Firefox 87\
3178 **CCK2 Equivalent:** N/A\

3190 Require or prevent using a primary (formerly master) password.
3192 If this value is true, a primary password is required. If this value is false, it works the same as if [`DisableMasterPasswordCreation`](#disablemasterpasswordcreation) was true and removes the primary password functionality.
3194 If both DisableMasterPasswordCreation and PrimaryPassword are used, DisableMasterPasswordCreation takes precedent.

3565 `Block` is a list of origins where the feature is not allowed.
3567 `BlockNewRequests` determines whether or not new requests can be made for the feature.

4017 Using the preference as the key, set the `Value` to the corresponding preference value.
4019 `Status` can be "default", "locked", "user" or "clear"
4021 Default preferences can be modified by the user.
4023 If a value is locked, it is also set as the default.
4025 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.
4027 User preferences persist even if the policy is removed, so if you need to remove them, you should use the clear policy.
4029 See the examples below for more detail.
4031 IMPORTANT: Make sure you're only setting a particular preference using this mechanism and not some other way.
