Bump version for release
[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`.

570 ### Certificates
571
572 ### Certificates | ImportEnterpriseRoots
573
574 Trust certificates that have been added to the operating system certificate store by a user or administrator.
575
576 Note: This policy only works on Windows and macOS. For Linux discussion, see [bug 1600509](https://bugzilla.mozilla.org/show_bug.cgi?id=1600509).
577
578 See https://support.mozilla.org/kb/setting-certificate-authorities-firefox for more detail.

617 ### Certificates | Install
618
619 Install certificates into the Firefox certificate store. If only a filename is specified, Firefox searches for the file in the following locations:
620
621 - Windows
622 - %USERPROFILE%\AppData\Local\Mozilla\Certificates
623 - %USERPROFILE%\AppData\Roaming\Mozilla\Certificates
624 - macOS
625 - /Library/Application Support/Mozilla/Certificates
626 - ~/Library/Application Support/Mozilla/Certificates
627 - Linux
628 - /usr/lib/mozilla/certificates
629 - /usr/lib64/mozilla/certificates
630 - ~/.mozilla/certificates
631
632 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.
633
634 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.
635
636 Certificates are installed using the trust string `CT,CT,`.
637
638 Binary (DER) and ASCII (PEM) certificates are both supported.

682 ### Cookies
683 Configure cookie preferences.
684
685 `Allow` is a list of origins (not domains) where cookies are always allowed. You must include http or https.
686
687 `AllowSession` is a list of origins (not domains) where cookies are only allowed for the current session. You must include http or https.
688
689 `Block` is a list of origins (not domains) where cookies are always blocked. You must include http or https.
690
691 `Default` determines whether cookies are accepted at all.
692
693 `AcceptThirdParty` determines how third-party cookies are handled.
694
695 `ExpireAtSessionEnd` determines when cookies expire.
696
697 `RejectTracker` only rejects cookies for trackers.
698
699 `Locked` prevents the user from changing cookie preferences.

1072 ### DisableDefaultBrowserAgent
1073 Prevent the default browser agent from taking any actions. Only applicable to Windows; other platforms don’t have the agent.
1074
1075 The browser agent is a Windows-only scheduled task which runs in the background to collect and submit data about the browser that the user has set as their OS default.

2250 ### ExtensionSettings
2251 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.
2252
2253 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.
2254
2255 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).
2256
2257 The configuration for each extension is another dictionary that can contain the fields documented below.
2258
2259 | Name | Description |
2260 | --- | --- |
2261 | `installation_mode` | Maps to a string indicating the installation mode for the extension. The valid strings are `allowed`,`blocked`,`force_installed`, and `normal_installed`.
2262 | &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.
2263 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`blocked`| Blocks installation of the extension and removes it from the device if already installed.
2264 | &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.
2265 | &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.
2266 | `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.
2267 | `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.
2268 | `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.
2269 | `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.
2270 | `restricted_domains` | An array of domains on which content scripts can't be run. This setting can be used only for the default configuration.
2271

2497 ### Handlers
2498 Configure default application handlers. This policy is based on the internal format of `handlers.json`.
2499
2500 You can configure handlers based on a mime type (`mimeTypes`), a file's extension (`extensions`), or a protocol (`schemes`).
2501
2502 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.
2503
2504 | Name | Description |
2505 | --- | --- |
2506 | `action`| Can be either `saveToDisk`, `useHelperApp`, `useSystemDefault`.
2507 | `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.
2508 | `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.
2509 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`name` | The display name of the handler (might not be used).
2510 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`path`| The native path to the executable to be used.
2511 | &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.

3529 ### Permissions
3530 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.
3531
3532 `Allow` is a list of origins where the feature is allowed.
3533
3534 `Block` is a list of origins where the feature is not allowed.
3535
3536 `BlockNewRequests` determines whether or not new requests can be made for the feature.
3537
3538 `Locked` prevents the user from changing preferences for the feature.
3539
3540 `Default` specifies the default value for Autoplay. block-audio-video is not supported on Firefox ESR 68.
3541
3542 **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)\
3543 **CCK2 Equivalent:** N/A\
3544 **Preferences Affected:** `permissions.default.camera`,`permissions.default.microphone`,`permissions.default.geo`,`permissions.default.desktop-notification`,`media.autoplay.default`.`permissions.default.xr`

3931 ### Preferences
3932 Set and lock preferences.
3933
3934 **NOTE** On Windows, in order to use this policy, you must clear all settings in the old **Preferences (Deprecated)** section.
3935
3936 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.
3937
3938 Preferences that start with the following prefixes are supported:
3939 ```
3940 accessibility.
3941 browser.
3942 datareporting.policy.
3943 dom.
3944 extensions.
3945 general.autoScroll (Firefox 83, Firefox ESR 78.5)
3946 general.smoothScroll (Firefox 83, Firefox ESR 78.5)
3947 geo.
3948 intl.
3949 layout.
3950 media.
3951 network.
3952 pdfjs. (Firefox 84, Firefox ESR 78.6)
3953 places.
3954 print.
3955 signon. (Firefox 83, Firefox ESR 78.5)
3956 spellchecker. (Firefox 84, Firefox ESR 78.6)
3957 ui.
3958 widget.
3959 ```
3960 as well as the following security preferences:
3961 | Preference | Type | Default
3962 | --- | --- | ---
3963 | security.default_personal_cert | string | Ask Every Time
3964 | &nbsp;&nbsp;&nbsp;&nbsp;If set to Select Automatically, Firefox automatically chooses the default personal certificate.
3965 | security.insecure_connection_text.enabled | bool | false
3966 | &nbsp;&nbsp;&nbsp;&nbsp;If set to true, adds the words "Not Secure" for insecure sites.
3967 | security.insecure_connection_text.pbmode.enabled | bool | false
3968 | &nbsp;&nbsp;&nbsp;&nbsp;If set to true, adds the words "Not Secure" for insecure sites in private browsing.
3969 | security.insecure_field_warning.contextual.enabled | bool | true
3970 | &nbsp;&nbsp;&nbsp;&nbsp;If set to false, remove the warning for inscure login fields.
3971 | security.mixed_content.block_active_content | boolean | true
3972 | &nbsp;&nbsp;&nbsp;&nbsp;If false, mixed active content (HTTP and HTTPS) is not blocked.
3973 | security.osclientcerts.autoload | boolean | false
3974 | &nbsp;&nbsp;&nbsp;&nbsp;If true, client certificates are loaded from the operating system certificate store.
3975 | security.ssl.errorReporting.enabled | boolean | true
3976 | &nbsp;&nbsp;&nbsp;&nbsp;If false, SSL errors cannot be sent to Mozilla.
3977 | security.tls.hello_downgrade_check | boolean | true
3978 | &nbsp;&nbsp;&nbsp;&nbsp;If false, the TLS 1.3 downgrade check is disabled.
3979 | security.warn_submit_secure_to_insecure | boolean | true
3980 | &nbsp;&nbsp;&nbsp;&nbsp;If false, no warning is shown when submitting s form from https to http.
3981 &nbsp;
3982
3983 Using the preference as the key, set the `Value` to the corresponding preference value.
3984
3985 `Status` can be "default", "locked", "user" or "clear"
3986
3987 Default preferences can be modified by the user.
3988
3989 If a value is locked, it is also set as the default.
3990
3991 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.
3992
3993 User preferences persist even if the policy is removed, so if you need to remove them, you should use the clear policy.
3994
3995 See the examples below for more detail.
3996
3997 IMPORTANT: Make sure you're only setting a particular preference using this mechanism and not some other way.
