[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 Official policy documentation has been moved to https://mozilla.github.io/policy-templates/.
6
7 I'm maintaining things in the README.md until we can update links in Firefox.
8
9 Firefox 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`.
10
11 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:
12
13 ```
14 {
15 "policies": {
16 "Authentication": {
17 "SPNEGO": ["mydomain.com", "https://myotherdomain.com"]
18 }
19 "Authentication_Comment": "These domains are required for us"
20 }
21 }
22 ```

497 ### AutoLaunchProtocolsFromOrigins
498 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.
499
500 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.
501
502 The schema is:
503 ```
504 {
505 "items": {
506 "properties": {
507 "allowed_origins": {
508 "items": {
509 "type": "string"

776
777 Note: [`ManagedBookmarks`](#managedbookmarks) is the new recommended way to add bookmarks. This policy will continue to be supported.
778
779 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.
780
781 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.

896
897 ### Certificates | ImportEnterpriseRoots
898
899 Trust certificates that have been added to the operating system certificate store by a user or administrator.
900
901 Note: This policy only works on Windows and macOS. For Linux discussion, see [bug 1600509](https://bugzilla.mozilla.org/show_bug.cgi?id=1600509).

942 ### Certificates | Install
943
944 Install certificates into the Firefox certificate store. If only a filename is specified, Firefox searches for the file in the following locations:
945
946 - Windows
947 - %USERPROFILE%\AppData\Local\Mozilla\Certificates
948 - %USERPROFILE%\AppData\Roaming\Mozilla\Certificates
949 - macOS
950 - /Library/Application Support/Mozilla/Certificates
951 - ~/Library/Application Support/Mozilla/Certificates
952 - Linux
953 - /usr/lib/mozilla/certificates
954 - /usr/lib64/mozilla/certificates
955 - ~/.mozilla/certificates
956
957 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.
958
959 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.
960
961 Certificates are installed using the trust string `CT,CT,`.
962
963 Binary (DER) and ASCII (PEM) certificates are both supported.

2494 ### EnableTrackingProtection
2495 Configure tracking protection.
2496
2497 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.
2498
2499 If `Value` is set to false, tracking protection is disabled and locked in both the regular browser and private browsing.
2500
2501 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.
2502
2503 If `Cryptomining` is set to true, cryptomining scripts on websites are blocked.
2504
2505 If `Fingerprinting` is set to true, fingerprinting scripts on websites are blocked.
2506
2507 If `EmailTracking` is set to true, hidden email tracking pixels and scripts on websites are blocked. (Firefox 112)
2508
2509 `Exceptions` are origins for which tracking protection is not enabled.
2510

2667
2668 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.

2728 ### Extensions
2729 Control the installation, uninstallation and locking of extensions.
2730
2731 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.
2732
2733 `Install` is a list of URLs or native paths for extensions to be installed.
2734
2735 `Uninstall` is a list of extension IDs that should be uninstalled if found.
2736
2737 `Locked` is a list of extension IDs that the user cannot disable or uninstall.

2811 ### ExtensionSettings
2812 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.
2813
2814 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.
2815
2816 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).
2817
2818 The configuration for each extension is another dictionary that can contain the fields documented below.
2819
2820 | Name | Description |
2821 | --- | --- |
2822 | `installation_mode` | Maps to a string indicating the installation mode for the extension. The valid strings are `allowed`,`blocked`,`force_installed`, and `normal_installed`.
2823 | &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.
2824 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`blocked`| Blocks installation of the extension and removes it from the device if already installed.
2825 | &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.
2826 | &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.
2827 | `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.
2828 | `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.
2829 | `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.
2830 | `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.
2831 | `restricted_domains` | An array of domains on which content scripts can't be run. This setting can be used only for the default configuration.
2832 | `updates_disabled` | (Firefox 89, Firefox ESR 78.11) Boolean that indicates whether or not to disable automatic updates for an individual extension.

3050 ### GoToIntranetSiteForSingleWordEntryInAddressBar
3051 Whether to always go through the DNS server before sending a single word search string to a search engine.
3052
3053 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.
3054
3055 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.
3056
3057 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.
3058
3059 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`.
3060
3061 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`.
3062

3064 **CCK2 Equivalent:** `N/A`\

3095 ### Handlers
3096 Configure default application handlers. This policy is based on the internal format of `handlers.json`.
3097
3098 You can configure handlers based on a mime type (`mimeTypes`), a file's extension (`extensions`), or a protocol (`schemes`).
3099
3100 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.
3101
3102 | Name | Description |
3103 | --- | --- |
3104 | `action`| Can be either `saveToDisk`, `useHelperApp`, `useSystemDefault`.
3105 | `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.
3106 | `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.
3107 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`name` | The display name of the handler (might not be used).
3108 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`path`| The native path to the executable to be used.
3109 | &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.

3774 1. The user will never be prompted to install updates
3775 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.
3776 3. The update UI will work as expected, unlike when using DisableAppUpdate.
3777
3778 This policy is primarily intended for advanced end users, not for enterprises.

4119
4120 ### PDFjs
4121 Disable or configure PDF.js, the built-in PDF viewer.
4122
4123 If `Enabled` is set to false, the built-in PDF viewer is disabled.
4124
4125 If `EnablePermissions` is set to true, the built-in PDF viewer will honor document permissions like preventing the copying of text.
4126
4127 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.

4171 ### Permissions
4172 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.
4173
4174 `Allow` is a list of origins where the feature is allowed.
4175
4176 `Block` is a list of origins where the feature is not allowed.
4177
4178 `BlockNewRequests` determines whether or not new requests can be made for the feature.
4179
4180 `Locked` prevents the user from changing preferences for the feature.
4181
4182 `Default` specifies the default value for Autoplay. block-audio-video is not supported on Firefox ESR 68.
4183
4184 **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)\
4185 **CCK2 Equivalent:** N/A\

4640
4641 Using the preference as the key, set the `Value` to the corresponding preference value.
4642
4643 `Status` can be "default", "locked", "user" or "clear"
4644
4645 * `"default"`: Read/Write: Settings appear as default even if factory default differs.
4646 * `"locked"`: Read-Only: Settings appear as default even if factory default differs.
4647 * `"user"`: Read/Write: Settings appear as changed if it differs from factory default.
4648 * `"clear"`: Read/Write: `Value` has no effect. Resets to factory defaults on each startup.
4649
4650 `"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```.
4651
4652 `"user"` preferences persist even if the policy is removed, so if you need to remove them, you should use the clear policy.
4653
4654 See the examples below for more detail.
4655
4656 IMPORTANT: Make sure you're only setting a particular preference using this mechanism and not some other way.

4987 ### Proxy
4988 Configure proxy settings. These settings correspond to the connection settings in Firefox preferences.
4989 To specify ports, append them to the hostnames with a colon (:).
4990
4991 Unless you lock this policy, changes the user already has in place will take effect.

5266 Previously, these values were always locked. Starting with Firefox 74 and Firefox ESR 68.6, you can use the `Locked` option to either keep the values unlocked (set it to false), or lock only the values you set (set it to true). If you want the old behavior of locking everything, do not set `Locked` at all.
