[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`.
6
7 Unfortunately, JSON files do not support comments, but you can add extra entries to the JSON to use as comments. You will see an error in about:policies, but the policies will still work properly. For example:
8
9 ```
10 {
11 "policies": {
12 "Authentication": {
13 "SPNEGO": ["mydomain.com", "https://myotherdomain.com"]
14 }
15 "Authentication_Comment": "These domains are required for us"
16 }
17 }
18 ```

494 ### AutoLaunchProtocolsFromOrigins
495 Define a list of external protocols that can be used from listed origins without prompting the user. The origin is the scheme plus the hostname.
496
497 The syntax of this policy is exactly the same as the [Chrome AutoLaunchProtocolsFromOrigins policy](https://cloud.google.com/docs/chrome-enterprise/policies/?policy=AutoLaunchProtocolsFromOrigins) except that you can only use valid origins (not just hostnames). This also means that you cannot specify an asterisk for all origins.
498
499 The schema is:
500 ```
501 {
502 "items": {
503 "properties": {
504 "allowed_origins": {
505 "items": {
506 "type": "string"

591
592 If set to false, the application will not try to install updates when the application is not running.

773
774 Note: [`ManagedBookmarks`](#managedbookmarks) is the new recommended way to add bookmarks. This policy will continue to be supported.
775
776 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.
777
778 If you want to clear all bookmarks set with this policy, you can set the value to an empty array (```[]```). This can be on Windows via the new Bookmarks (JSON) policy available with GPO and Intune.

892 ### Certificates
893
894 ### Certificates | ImportEnterpriseRoots
895
896 Trust certificates that have been added to the operating system certificate store by a user or administrator.
897
898 Note: This policy only works on Windows and macOS. For Linux discussion, see [bug 1600509](https://bugzilla.mozilla.org/show_bug.cgi?id=1600509).

939 ### Certificates | Install
940
941 Install certificates into the Firefox certificate store. If only a filename is specified, Firefox searches for the file in the following locations:
942
943 - Windows
944 - %USERPROFILE%\AppData\Local\Mozilla\Certificates
945 - %USERPROFILE%\AppData\Roaming\Mozilla\Certificates
946 - macOS
947 - /Library/Application Support/Mozilla/Certificates
948 - ~/Library/Application Support/Mozilla/Certificates
949 - Linux
950 - /usr/lib/mozilla/certificates
951 - /usr/lib64/mozilla/certificates
952 - ~/.mozilla/certificates
953
954 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.
955
956 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.
957
958 Certificates are installed using the trust string `CT,CT,`.
959
960 Binary (DER) and ASCII (PEM) certificates are both supported.

2491 ### EnableTrackingProtection
2492 Configure tracking protection.
2493
2494 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.
2495
2496 If `Value` is set to false, tracking protection is disabled and locked in both the regular browser and private browsing.
2497
2498 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.
2499
2500 If `Cryptomining` is set to true, cryptomining scripts on websites are blocked.
2501
2502 If `Fingerprinting` is set to true, fingerprinting scripts on websites are blocked.
2503
2504 If `EmailTracking` is set to true, hidden email tracking pixels and scripts on websites are blocked. (Firefox 112)
2505
2506 `Exceptions` are origins for which tracking protection is not enabled.
2507
2508 **Compatibility:** Firefox 60, Firefox ESR 60 (Cryptomining and Fingerprinting added in 70/68.2, Exceptions added in 73/68.5)\

2664
2665 Important: The documentation for the policy for both Edge and Chrome is incorrect. The ```domains``` value must be a domain, not a URL pattern. Also, we do not support using ```*``` to mean all domains.

2725 ### Extensions
2726 Control the installation, uninstallation and locking of extensions.
2727
2728 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.
2729
2730 `Install` is a list of URLs or native paths for extensions to be installed.
2731
2732 `Uninstall` is a list of extension IDs that should be uninstalled if found.
2733
2734 `Locked` is a list of extension IDs that the user cannot disable or uninstall.

2808 ### ExtensionSettings
2809 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.
2810
2811 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.
2812
2813 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).
2814
2815 The configuration for each extension is another dictionary that can contain the fields documented below.
2816
2817 | Name | Description |
2818 | --- | --- |
2819 | `installation_mode` | Maps to a string indicating the installation mode for the extension. The valid strings are `allowed`,`blocked`,`force_installed`, and `normal_installed`.
2820 | &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.
2821 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`blocked`| Blocks installation of the extension and removes it from the device if already installed.
2822 | &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.
2823 | &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.
2824 | `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.
2825 | `install_sources` | A list of sources from which installing extensions is allowed using URL match patterns. **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.
2826 | `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.
2827 | `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.
2828 | `restricted_domains` | An array of domains on which content scripts can't be run. This setting can be used only for the default configuration.
2829 | `updates_disabled` | (Firefox 89, Firefox ESR 78.11) Boolean that indicates whether or not to disable automatic updates for an individual extension.
2830 | `default_area` | (Firefox 113) This settings specifies where the extension icon should be placed. Possible values are "navbar" and "menupanel"
2831

3129 ### GoToIntranetSiteForSingleWordEntryInAddressBar
3130 Whether to always go through the DNS server before sending a single word search string to a search engine.
3131
3132 If the site exists, it will navigate to the website. If the intranet responds with a 404, the page will show a 404. If the intranet does not respond, the browser will attempt a search.
3133
3134 The second result in the URL bar will be a search result to allow users to conduct a web search exactly as it was entered.
3135
3136 If instead you would like to enable the ability to have your domain appear as a valid URL and to disallow the browser from ever searching that term using the first result that matches it, add the pref `browser.fixup.domainwhitelist.YOUR_DOMAIN` (where `YOUR_DOMAIN` is the name of the domain you'd like to add), and set the pref to `true`. The URL bar will then suggest `YOUR_DOMAIN` when the user fully types `YOUR_DOMAIN`. If the user attempts to load that domain and it fails to load, it will show an "Unable to connect" error page.
3137
3138 You can also whitelist a domain suffix that is not part of the [Public Suffix List](https://publicsuffix.org/) by adding the pref `browser.fixup.domainsuffixwhitelist.YOUR_DOMAIN_SUFFIX` with a value of `true`.
3139
3140 Additionally, if you want users to see a "Did you mean to go to 'YOUR_DOMAIN'" prompt below the URL bar if they land on a search results page instead of an intranet domain that provides a response, set the pref `browser.urlbar.dnsResolveSingleWordsAfterSearch` to `1`. Enabling this will cause the browser to commit a DNS check after every single word search. If the browser receives a response from the intranet, a prompt will ask the user if they'd like to instead navigate to `YOUR_DOMAIN`. If the user presses the **yes** button, `browser.fixup.domainwhitelist.YOUR_DOMAIN` will be set to `true`.
3141
3142 **Compatibility:** Firefox 104, Firefox ESR 102.2\
3143 **CCK2 Equivalent:** `N/A`\

3174 ### Handlers
3175 Configure default application handlers. This policy is based on the internal format of `handlers.json`.
3176
3177 You can configure handlers based on a mime type (`mimeTypes`), a file's extension (`extensions`), or a protocol (`schemes`).
3178
3179 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.
3180
3181 | Name | Description |
3182 | --- | --- |
3183 | `action`| Can be either `saveToDisk`, `useHelperApp`, `useSystemDefault`.
3184 | `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.
3185 | `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.
3186 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`name` | The display name of the handler (might not be used).
3187 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`path`| The native path to the executable to be used.
3188 | &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.

3853 1. The user will never be prompted to install updates
3854 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.
3855 3. The update UI will work as expected, unlike when using DisableAppUpdate.
3856

4202 If `Enabled` is set to false, the built-in PDF viewer is disabled.
4203
4204 If `EnablePermissions` is set to true, the built-in PDF viewer will honor document permissions like preventing the copying of text.
4205
4206 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.

4250 ### Permissions
4251 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.
4252
4253 `Allow` is a list of origins where the feature is allowed.
4254
4255 `Block` is a list of origins where the feature is not allowed.
4256
4257 `BlockNewRequests` determines whether or not new requests can be made for the feature.
4258
4259 `Locked` prevents the user from changing preferences for the feature.
4260
4261 `Default` specifies the default value for Autoplay. block-audio-video is not supported on Firefox ESR 68.
4262
4263 **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)\

4652 ### Preferences
4653 Set and lock preferences.
4654
4655 **NOTE** On Windows, in order to use this policy, you must clear all settings in the old **Preferences (Deprecated)** section.
4656
4657 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.
4658
4659 Preferences that start with the following prefixes are supported:
4660 ```
4661 accessibility.
4662 app.update.* (Firefox 86, Firefox 78.8)
4663 browser.
4664 datareporting.policy.
4665 dom.
4666 extensions.
4667 general.autoScroll (Firefox 83, Firefox ESR 78.5)

4683 ui.
4684 widget.
4685 xpinstall.signatures.required (Firefox ESR 102.10, Firefox ESR only)
4686 ```
4687 as well as the following security preferences:
4688 | Preference | Type | Default
4689 | --- | --- | ---
4690 | security.default_personal_cert | string | Ask Every Time
4691 | &nbsp;&nbsp;&nbsp;&nbsp;If set to Select Automatically, Firefox automatically chooses the default personal certificate.
4692 | security.insecure_connection_text.enabled | bool | false
4693 | &nbsp;&nbsp;&nbsp;&nbsp;If set to true, adds the words "Not Secure" for insecure sites.
4694 | security.insecure_connection_text.pbmode.enabled | bool | false
4695 | &nbsp;&nbsp;&nbsp;&nbsp;If set to true, adds the words "Not Secure" for insecure sites in private browsing.
4696 | security.mixed_content.block_active_content | boolean | true
4697 | &nbsp;&nbsp;&nbsp;&nbsp;If false, mixed active content (HTTP and HTTPS) is not blocked.
4698 | security.osclientcerts.autoload | boolean | false
4699 | &nbsp;&nbsp;&nbsp;&nbsp;If true, client certificates are loaded from the operating system certificate store.
4700 | security.OCSP.enabled | integer | 1
4701 | &nbsp;&nbsp;&nbsp;&nbsp;If 0, do not fetch OCSP. If 1, fetch OCSP for DV and EV certificates. If 2, fetch OCSP only for EV certificates
4702 | security.OCSP.require | boolean | false
4703 | &nbsp;&nbsp;&nbsp;&nbsp; If true, if an OCSP request times out, the connection fails.
4704 | security.ssl.enable_ocsp_stapling | boolean | true
4705 | &nbsp;&nbsp;&nbsp;&nbsp; If false, OCSP stapling is not enabled.
4706 | security.ssl.errorReporting.enabled | boolean | true
4707 | &nbsp;&nbsp;&nbsp;&nbsp;If false, SSL errors cannot be sent to Mozilla.
4708 | security.tls.enable_0rtt_data | boolean | true
4709 | &nbsp;&nbsp;&nbsp;&nbsp;If false, TLS early data is turned off (Firefox 93, Firefox 91.2, Firefox 78.15).
4710 | security.tls.hello_downgrade_check | boolean | true
4711 | &nbsp;&nbsp;&nbsp;&nbsp;If false, the TLS 1.3 downgrade check is disabled.
4712 | security.tls.version.enable-deprecated | boolean | false
4713 | &nbsp;&nbsp;&nbsp;&nbsp;If true, browser will accept TLS 1.0. and TLS 1.1 (Firefox 86, Firefox 78.8).
4714 | security.warn_submit_secure_to_insecure | boolean | true
4715 | &nbsp;&nbsp;&nbsp;&nbsp;If false, no warning is shown when submitting a form from https to http.
4716 &nbsp;
4717
4718 Using the preference as the key, set the `Value` to the corresponding preference value.
4719
4720 `Status` can be "default", "locked", "user" or "clear"
4721
4722 * `"default"`: Read/Write: Settings appear as default even if factory default differs.
4723 * `"locked"`: Read-Only: Settings appear as default even if factory default differs.
4724 * `"user"`: Read/Write: Settings appear as changed if it differs from factory default.
4725 * `"clear"`: Read/Write: `Value` has no effect. Resets to factory defaults on each startup.
4726
4727 `"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. An example of this is ```toolkit.legacyUserProfileCustomizations.stylesheets```.
4728
4729 `"user"` preferences persist even if the policy is removed, so if you need to remove them, you should use the clear policy.
4730
4731 See the examples below for more detail.
4732
4733 IMPORTANT: Make sure you're only setting a particular preference using this mechanism and not some other way.

5063 ### Proxy
5064 Configure proxy settings. These settings correspond to the connection settings in Firefox preferences.
5065 To specify ports, append them to the hostnames with a colon (:).
5066
5067 Unless you lock this policy, changes the user already has in place will take effect.
5068
5069 `Mode` is the proxy method being used.
5070
5071 `Locked` is whether or not proxy settings can be changed.
5072
5073 `HTTPProxy` is the HTTP proxy server.
5074
5075 `UseHTTPProxyForAllProtocols` is whether or not the HTTP proxy should be used for all other proxies.
5076
5077 `SSLProxy` is the SSL proxy server.
5078
5079 `FTPProxy` is the FTP proxy server.
5080
5081 `SOCKSProxy` is the SOCKS proxy server
5082
5083 `SOCKSVersion` is the SOCKS version (4 or 5)
5084
5085 `Passthrough` is list of hostnames or IP addresses that will not be proxied. Use `<local>` to bypass proxying for all hostnames which do not contain periods.
5086
5087 `AutoConfigURL` is a URL for proxy configuration (only used if Mode is autoConfig).
5088
5089 `AutoLogin` means do not prompt for authentication if password is saved.
5090
5091 `UseProxyForDNS` to use proxy DNS when using SOCKS v5.
