[policy-templates.git] / README.md
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`.

614 ### Certificates | Install
615
616 Install certificates into the Firefox certificate store. If only a filename is specified, Firefox searches for the file in the following locations:
617
618 - Windows
619 - %USERPROFILE%\AppData\Local\Mozilla\Certificates
620 - %USERPROFILE%\AppData\Roaming\Mozilla\Certificates
621 - macOS
622 - /Library/Application Support/Mozilla/Certificates
623 - ~/Library/Application Support/Mozilla/Certificates
624 - Linux
625 - /usr/lib/mozilla/certificates
626 - /usr/lib64/mozilla/certificates
627 - ~/.mozilla/certificates
628
629 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.
630
631 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.
632
633 Certificates are installed using the trust string `CT,CT,`.
634
635 Binary (DER) and ASCII (PEM) certificates are both supported.

679 ### Cookies
680 Configure cookie preferences.
681
682 `Allow` is a list of origins (not domains) where cookies are always allowed. You must include http or https.
683
684 `AllowSession` is a list of origins (not domains) where cookies are only allowed for the current session. You must include http or https.
685
686 `Block` is a list of origins (not domains) where cookies are always blocked. You must include http or https.
687
688 `Default` determines whether cookies are accepted at all.
689
690 `AcceptThirdParty` determines how third-party cookies are handled.
691
692 `ExpireAtSessionEnd` determines when cookies expire.
693
694 `RejectTracker` only rejects cookies for trackers.
695
696 `Locked` prevents the user from changing cookie preferences.

2243 ### ExtensionSettings
2244 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.
2245
2246 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.
2247
2248 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).
2249
2250 The configuration for each extension is another dictionary that can contain the fields documented below.
2251
2252 | Name | Description |
2253 | --- | --- |
2254 | `installation_mode` | Maps to a string indicating the installation mode for the extension. The valid strings are `allowed`,`blocked`,`force_installed`, and `normal_installed`.
2255 | &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.
2256 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`blocked`| Blocks installation of the extension and removes it from the device if already installed.
2257 | &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.
2258 | &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.
2259 | `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.
2260 | `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.
2261 | `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.
2262 | `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.
2263 | `restricted_domains` | An array of domains on which content scripts can't be run. This setting can be used only for the default configuration.

2490 ### Handlers
2491 Configure default application handlers. This policy is based on the internal format of `handlers.json`.
2492
2493 You can configure handlers based on a mime type (`mimeTypes`), a file's extension (`extensions`), or a protocol (`schemes`).
2494
2495 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.
2496
2497 | Name | Description |
2498 | --- | --- |
2499 | `action`| Can be either `saveToDisk`, `useHelperApp`, `useSystemDefault`.
2500 | `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.
2501 | `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.
2502 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`name` | The display name of the handler (might not be used).
2503 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`path`| The native path to the executable to be used.
2504 | &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.

2925 ### LegacyProfiles
2926 Disable the feature enforcing a separate profile for each installation.
2927
2928 If this policy set to true, Firefox will not try to create different profiles for installations of Firefox in different directories. This is the equivalent of the MOZ_LEGACY_PROFILES environment variable.
2929
2930 If this policy set to false, Firefox will create a new profile for each unique installation of Firefox.
2931
2932 This policy only work on Windows via GPO (not policies.json).

2992 ### PrimaryPassword
2993 Require or prevent using a primary (formerly master) password.
2994
2995 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.
2996
2997 If both DisableMasterPasswordCreation and PrimaryPassword are used, DisableMasterPasswordCreation takes precedent.

3317
3318 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.

3361 ### Permissions
3362 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.
3363
3364 `Allow` is a list of origins where the feature is allowed.
3365
3366 `Block` is a list of origins where the feature is not allowed.
3367
3368 `BlockNewRequests` determines whether or not new requests can be made for the feature.
3369
3370 `Locked` prevents the user from changing preferences for the feature.
3371
3372 `Default` specifies the default value for Autoplay. block-audio-video is not supported on Firefox ESR 68.
3373
3374 **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)\

3752 ### Preferences
3753 Set and lock preferences.
3754
3755 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.
3756
3757 Preferences that start with the following prefixes are supported:
3758 ```
3759 accessibility.
3760 browser.
3761 datareporting.policy.
3762 dom.
3763 extensions.
3764 geo.
3765 intl.
3766 layout.
3767 media.
3768 network.
3769 places.
3770 print.
3771 ui.
3772 widget.
3773 ```
3774 as well as the following security preferences:
3775 ```
3776 security.default_personal_cert
3777 security.insecure_connection_text.enabled
3778 security.insecure_connection_text.pbmode.enabled
3779 security.insecure_field_warning.contextual.enabled
3780 security.mixed_content.block_active_content
3781 security.osclientcerts.autoload
3782 security.ssl.errorReporting.enabled
3783 security.tls.hello_downgrade_check
3784 security.warn_submit_secure_to_insecure
3785 ```
3786 Using the preference as the key, set the `Value` to the corresponding preference value.
3787
3788 `Status` can be "default", "locked", "user" or "clear"
3789
3790 Default preferences can be modified by the user.
3791
3792 If a value is locked, it is also set as the default.
3793
3794 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.
3795
3796 User preferences persist even if the policy is removed, so if you need to remove them, you should use the clear policy.
3797
3798 See the examples below for more detail.
3799
3800 IMPORTANT: Make sure you're only setting a particular preference using this mechanism and not some other way.
