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`.

667 ### Certificates | Install
669 Install certificates into the Firefox certificate store. If only a filename is specified, Firefox searches for the file in the following locations:
672 - %USERPROFILE%\AppData\Local\Mozilla\Certificates
673 - %USERPROFILE%\AppData\Roaming\Mozilla\Certificates
675 - /Library/Application Support/Mozilla/Certificates
676 - ~/Library/Application Support/Mozilla/Certificates
678 - /usr/lib/mozilla/certificates
679 - /usr/lib64/mozilla/certificates
680 - ~/.mozilla/certificates
682 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.
684 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.
686 Certificates are installed using the trust string `CT,CT,`.
688 Binary (DER) and ASCII (PEM) certificates are both supported.

2059 Configure tracking protection.
2061 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.
2063 If `Value` is set to false, tracking protection is disabled and locked in both the regular browser and private browsing.
2065 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.
2067 If `Cryptomining` is set to true, cryptomining scripts on websites are blocked.
2069 If `Fingerprinting` is set to true, fingerprinting scripts on websites are blocked.

2224 Control the installation, uninstallation and locking of extensions.
2226 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.
2228 `Install` is a list of URLs or native paths for extensions to be installed.
2230 `Uninstall` is a list of extension IDs that should be uninstalled if found.
2232 `Locked` is a list of extension IDs that the user cannot disable or uninstall.

2306 ### ExtensionSettings
2307 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.
2309 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.
2311 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).
2313 The configuration for each extension is another dictionary that can contain the fields documented below.
2315 | Name | Description |
2317 | `installation_mode` | Maps to a string indicating the installation mode for the extension. The valid strings are `allowed`,`blocked`,`force_installed`, and `normal_installed`.
2318 | `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.
2319 | `blocked`| Blocks installation of the extension and removes it from the device if already installed.
2320 | `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.
2321 | `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.
2322 | `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.
2323 | `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.
2324 | `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.
2325 | `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.
2326 | `restricted_domains` | An array of domains on which content scripts can't be run. This setting can be used only for the default configuration.
2328 **Compatibility:** Firefox 69, Firefox ESR 68.1 (As of Firefox 85, Firefox ESR 78.7, installing a theme makes it the default.)\

2558 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.
2560 | Name | Description |
2562 | `action`| Can be either `saveToDisk`, `useHelperApp`, `useSystemDefault`.
2563 | `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.
2564 | `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.
2565 | `name` | The display name of the handler (might not be used).
2566 | `path`| The native path to the executable to be used.
2567 | `uriTemplate`| A url to a web based application handler. The URL must be https and contain a %s to be used for substitution.

3214 ### ManualAppUpdateOnly
3216 Switch to manual updates only.
3218 If this policy is enabled:
3219 1. The user will never be prompted to install updates
3220 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.
3221 3. The update UI will work as expected, unlike when using DisableAppUpdate.
3223 This policy is primarily intended for advanced end users, not for enterprises.
3225 **Compatibility:** Firefox 87\
3226 **CCK2 Equivalent:** N/A\

3238 Require or prevent using a primary (formerly master) password.
3240 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.
3242 If both DisableMasterPasswordCreation and PrimaryPassword are used, DisableMasterPasswordCreation takes precedent.

4014 Set and lock preferences.
4016 **NOTE** On Windows, in order to use this policy, you must clear all settings in the old **Preferences (Deprecated)** section.
4018 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.
4020 Preferences that start with the following prefixes are supported:
4023 app.update.* (Firefox 86, Firefox 78.8)
4025 datareporting.policy.
4028 general.autoScroll (Firefox 83, Firefox ESR 78.5)
4029 general.smoothScroll (Firefox 83, Firefox ESR 78.5)
4035 pdfjs. (Firefox 84, Firefox ESR 78.6)
4038 signon. (Firefox 83, Firefox ESR 78.5)
4039 spellchecker. (Firefox 84, Firefox ESR 78.6)
4043 as well as the following security preferences:
4044 | Preference | Type | Default
4046 | security.default_personal_cert | string | Ask Every Time
4047 | If set to Select Automatically, Firefox automatically chooses the default personal certificate.
4048 | security.insecure_connection_text.enabled | bool | false
4049 | If set to true, adds the words "Not Secure" for insecure sites.
4050 | security.insecure_connection_text.pbmode.enabled | bool | false
4051 | If set to true, adds the words "Not Secure" for insecure sites in private browsing.
4052 | security.insecure_field_warning.contextual.enabled | bool | true
4053 | If set to false, remove the warning for inscure login fields.
4054 | security.mixed_content.block_active_content | boolean | true
4055 | If false, mixed active content (HTTP and HTTPS) is not blocked.
4056 | security.osclientcerts.autoload | boolean | false
4057 | If true, client certificates are loaded from the operating system certificate store.
4058 | security.ssl.errorReporting.enabled | boolean | true
4059 | If false, SSL errors cannot be sent to Mozilla.
4060 | security.tls.hello_downgrade_check | boolean | true
4061 | If false, the TLS 1.3 downgrade check is disabled.
4062 | security.tls.version.enable-deprecated | boolean | false
4063 | If true, browser will accept TLS 1.0. and TLS 1.1 (Firefox 86, Firefox 78.8)
4064 | security.warn_submit_secure_to_insecure | boolean | true
4065 | If false, no warning is shown when submitting s form from https to http.
4068 Using the preference as the key, set the `Value` to the corresponding preference value.
4070 `Status` can be "default", "locked", "user" or "clear"
4072 Default preferences can be modified by the user.
4074 If a value is locked, it is also set as the default.
4076 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.
4078 User preferences persist even if the policy is removed, so if you need to remove them, you should use the clear policy.
4080 See the examples below for more detail.
4082 IMPORTANT: Make sure you're only setting a particular preference using this mechanism and not some other way.
