   1 **These policies are in active development and so might contain changes that do not work with current versions of Firefox.**
   2
   3 **You should use the [officially released versions](https://github.com/mozilla/policy-templates/releases) if you are deploying changes.**
   4
   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`.

 518
 519 Note: [`ManagedBookmarks`](#managedbookmarks) is the new recommended way to add bookmarks. This policy will continue to be supported.
 520
 521 Add bookmarks in either the bookmarks toolbar or menu. Only `Title` and `URL` are required. If `Placement` is not specified, the bookmark will be placed on the toolbar. If `Folder` is specified, it is automatically created and bookmarks with the same folder name are grouped together.

 620 ### Certificates
 621
 622 ### Certificates | ImportEnterpriseRoots
 623
 624 Trust certificates that have been added to the operating system certificate store by a user or administrator.
 625
 626 Note: This policy only works on Windows and macOS. For Linux discussion, see [bug 1600509](https://bugzilla.mozilla.org/show_bug.cgi?id=1600509).

 666 ```
 667 ### Certificates | Install
 668
 669 Install certificates into the Firefox certificate store. If only a filename is specified, Firefox searches for the file in the following locations:
 670
 671 - Windows
 672   - %USERPROFILE%\AppData\Local\Mozilla\Certificates
 673   - %USERPROFILE%\AppData\Roaming\Mozilla\Certificates
 674 - macOS
 675   - /Library/Application Support/Mozilla/Certificates
 676   - ~/Library/Application Support/Mozilla/Certificates
 677 - Linux
 678   - /usr/lib/mozilla/certificates
 679   - /usr/lib64/mozilla/certificates
 680   - ~/.mozilla/certificates
 681
 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.
 683
 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.
 685
 686 Certificates are installed using the trust string `CT,CT,`.
 687
 688 Binary (DER) and ASCII (PEM) certificates are both supported.

 732 ### Cookies
 733 Configure cookie preferences.
 734
 735 `Allow` is a list of origins (not domains) where cookies are always allowed. You must include http or https.
 736
 737 `AllowSession` is a list of origins (not domains) where cookies are only allowed for the current session. You must include http or https.
 738
 739 `Block` is a list of origins (not domains) where cookies are always blocked. You must include http or https.
 740
 741 `Default` determines whether cookies are accepted at all.
 742
 743 `AcceptThirdParty` determines how third-party cookies are handled.
 744
 745 `ExpireAtSessionEnd` determines when cookies expire.
 746
 747 `RejectTracker` only rejects cookies for trackers.
 748
 749 `Locked` prevents the user from changing cookie preferences.

2223 ### Extensions
2224 Control the installation, uninstallation and locking of extensions.
2225
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.
2227
2228 `Install` is a list of URLs or native paths for extensions to be installed.
2229
2230 `Uninstall` is a list of extension IDs that should be uninstalled if found.
2231
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.
2308
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.
2310
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).
2312
2313 The configuration for each extension is another dictionary that can contain the fields documented below.
2314
2315 | Name | Description |
2316 | --- | --- |
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 | &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.
2319 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`blocked`| Blocks installation of the extension and removes it from the device if already installed.
2320 | &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.
2321 | &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.
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.
2327 | `updates_disabled` | (Firefox 88, Firefox ESR 78.11) Disable automatic updates for an individual extension.
2328
2329 **Compatibility:** Firefox 69, Firefox ESR 68.1 (As of Firefox 85, Firefox ESR 78.7, installing a theme makes it the default.)\

2554 ### Handlers
2555 Configure default application handlers. This policy is based on the internal format of `handlers.json`.
2556
2557 You can configure handlers based on a mime type (`mimeTypes`), a file's extension (`extensions`), or a protocol (`schemes`).
2558
2559 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
2561 | Name | Description |
2562 | --- | --- |
2563 | `action`| Can be either `saveToDisk`, `useHelperApp`, `useSystemDefault`.
2564 | `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.
2565 | `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.
2566 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`name` | The display name of the handler (might not be used).
2567 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`path`| The native path to the executable to be used.
2568 | &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.

3215 ### ManualAppUpdateOnly
3216
3217 Switch to manual updates only.
3218
3219 If this policy is enabled:
3220  1. The user will never be prompted to install updates
3221  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.
3222  3. The update UI will work as expected, unlike when using DisableAppUpdate.
3223
3224 This policy is primarily intended for advanced end users, not for enterprises.
3225
3226 **Compatibility:** Firefox 87\

3238 ### PrimaryPassword
3239 Require or prevent using a primary (formerly master) password.
3240
3241 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
3243 If both DisableMasterPasswordCreation and PrimaryPassword are used, DisableMasterPasswordCreation takes precedent.

3567
3568 Note: DisableBuiltinPDFViewer has not been deprecated. You can either continue to use it, or switch to using PDFjs->Enabled to disable the built-in PDF viewer. This new permission was added because we needed a place for PDFjs->EnabledPermissions.

3612 ### Permissions
3613 Set permissions associated with camera, microphone, location, notifications, autoplay, and virtual reality. Because these are origins, not domains, entries with unique ports must be specified separately. This explicitly means that it is not possible to add wildcards. See examples below.
3614
3615 `Allow` is a list of origins where the feature is allowed.
3616
3617 `Block` is a list of origins where the feature is not allowed.
3618
3619 `BlockNewRequests` determines whether or not new requests can be made for the feature.
3620
3621 `Locked` prevents the user from changing preferences for the feature.
3622
3623 `Default` specifies the default value for Autoplay. block-audio-video is not supported on Firefox ESR 68.
3624
3625 **Compatibility:** Firefox 62, Firefox ESR 60.2 (Autoplay added in Firefox 74, Firefox ESR 68.6, Autoplay Default/Locked added in Firefox 76, Firefox ESR 68.8, VirtualReality added in Firefox 80, Firefox ESR 78.2)\

4014 ### Preferences
4015 Set and lock preferences.
4016
4017 **NOTE** On Windows, in order to use this policy, you must clear all settings in the old **Preferences (Deprecated)** section.
4018
4019 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
4021 Preferences that start with the following prefixes are supported:
4022 ```
4023 accessibility.
4024 app.update.* (Firefox 86, Firefox 78.8)
4025 browser.
4026 datareporting.policy.
4027 dom.
4028 extensions.
4029 general.autoScroll (Firefox 83, Firefox ESR 78.5)
4030 general.smoothScroll (Firefox 83, Firefox ESR 78.5)
4031 geo.
4032 gfx.
4033 intl.
4034 layers.
4035 layout.
4036 media.
4037 network.
4038 pdfjs. (Firefox 84, Firefox ESR 78.6)
4039 places.
4040 print.
4041 signon. (Firefox 83, Firefox ESR 78.5)
4042 spellchecker. (Firefox 84, Firefox ESR 78.6)
4043 ui.
4044 widget.
4045 ```
4046 as well as the following security preferences:
4047 | Preference | Type | Default
4048 | --- | --- | ---
4049 | security.default_personal_cert | string | Ask Every Time
4050 | &nbsp;&nbsp;&nbsp;&nbsp;If set to Select Automatically, Firefox automatically chooses the default personal certificate.
4051 | security.insecure_connection_text.enabled | bool | false
4052 | &nbsp;&nbsp;&nbsp;&nbsp;If set to true, adds the words "Not Secure" for insecure sites.
4053 | security.insecure_connection_text.pbmode.enabled | bool | false
4054 | &nbsp;&nbsp;&nbsp;&nbsp;If set to true, adds the words "Not Secure" for insecure sites in private browsing.
4055 | security.insecure_field_warning.contextual.enabled | bool | true
4056 | &nbsp;&nbsp;&nbsp;&nbsp;If set to false, remove the warning for inscure login fields.
4057 | security.mixed_content.block_active_content | boolean | true
4058 | &nbsp;&nbsp;&nbsp;&nbsp;If false, mixed active content (HTTP and HTTPS) is not blocked.
4059 | security.osclientcerts.autoload | boolean | false
4060 | &nbsp;&nbsp;&nbsp;&nbsp;If true, client certificates are loaded from the operating system certificate store.
4061 | security.ssl.errorReporting.enabled | boolean | true
4062 | &nbsp;&nbsp;&nbsp;&nbsp;If false, SSL errors cannot be sent to Mozilla.
4063 | security.tls.hello_downgrade_check | boolean | true
4064 | &nbsp;&nbsp;&nbsp;&nbsp;If false, the TLS 1.3 downgrade check is disabled.
4065 | security.tls.version.enable-deprecated | boolean | false
4066 | &nbsp;&nbsp;&nbsp;&nbsp;If true, browser will accept TLS 1.0. and TLS 1.1 (Firefox 86, Firefox 78.8)
4067 | security.warn_submit_secure_to_insecure | boolean | true
4068 | &nbsp;&nbsp;&nbsp;&nbsp;If false, no warning is shown when submitting s form from https to http.
4069 &nbsp;
4070
4071 Using the preference as the key, set the `Value` to the corresponding preference value.
4072
4073 `Status` can be "default", "locked", "user" or "clear"
4074
4075 Default preferences can be modified by the user.
4076
4077 If a value is locked, it is also set as the default.
4078
4079 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.
4080
4081 User preferences persist even if the policy is removed, so if you need to remove them, you should use the clear policy.
4082
4083 See the examples below for more detail.
4084
4085 IMPORTANT: Make sure you're only setting a particular preference using this mechanism and not some other way.
