   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`.

 479 ### AutoLaunchProtocolsFromOrigins
 480 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.
 481
 482 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.
 483
 484 The schema is:
 485 ```
 486 {
 487  "items": {
 488   "properties": {
 489    "allowed_origins": {
 490     "items": {

 757 ### Bookmarks
 758
 759 Note: [`ManagedBookmarks`](#managedbookmarks) is the new recommended way to add bookmarks. This policy will continue to be supported.
 760
 761 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.
 762
 763 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.

 924 ### Certificates | Install
 925
 926 Install certificates into the Firefox certificate store. If only a filename is specified, Firefox searches for the file in the following locations:
 927
 928 - Windows
 929   - %USERPROFILE%\AppData\Local\Mozilla\Certificates
 930   - %USERPROFILE%\AppData\Roaming\Mozilla\Certificates
 931 - macOS
 932   - /Library/Application Support/Mozilla/Certificates
 933   - ~/Library/Application Support/Mozilla/Certificates
 934 - Linux
 935   - /usr/lib/mozilla/certificates
 936   - /usr/lib64/mozilla/certificates
 937   - ~/.mozilla/certificates
 938
 939 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.
 940
 941 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.
 942
 943 Certificates are installed using the trust string `CT,CT,`.
 944
 945 Binary (DER) and ASCII (PEM) certificates are both supported.

 995
 996 `Block` is a list of origins (not domains) where cookies are always blocked. You must include http or https.
 997
 998 `Behavior` sets the default behavior for cookies based on the values below.
 999
1000 `BehaviorPrivateBrowsing` sets the default behavior for cookies in private browsing based on the values below.
1001
1002 | Value | Description
1003 | --- | ---
1004 | accept | Accept all cookies
1005 | reject-foreign | Reject third party cookies
1006 | reject | Reject all cookies

1008 | reject-tracker | Reject cookies for known trackers (default)
1009 | reject-tracker-and-partition-foreign | Reject cookies for known trackers and partition third-party cookies (Total Cookie Protection) (default for private browsing)
1010
1011 `Default` (Deprecated) determines whether cookies are accepted at all.
1012
1013 `AcceptThirdParty` (Deprecated) determines how third-party cookies are handled.
1014
1015 `ExpireAtSessionEnd` determines when cookies expire.
1016
1017 `RejectTracker` (Deprecated) only rejects cookies for trackers.
1018
1019 `Locked` prevents the user from changing cookie preferences.

2367 ### EnableTrackingProtection
2368 Configure tracking protection.
2369
2370 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.
2371
2372 If `Value` is set to false, tracking protection is disabled and locked in both the regular browser and private browsing.
2373
2374 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.
2375
2376 If `Cryptomining` is set to true, cryptomining scripts on websites are blocked.
2377
2378 If `Fingerprinting` is set to true, fingerprinting scripts on websites are blocked.
2379
2380 `Exceptions` are origins for which tracking protection is not enabled.

2537 This policy is based on the [Chrome policy](https://chromeenterprise.google/policies/#ExemptDomainFileTypePairsFromFileTypeDownloadWarnings) of the same name.
2538
2539 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.

2599 ### Extensions
2600 Control the installation, uninstallation and locking of extensions.
2601
2602 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.
2603
2604 `Install` is a list of URLs or native paths for extensions to be installed.
2605
2606 `Uninstall` is a list of extension IDs that should be uninstalled if found.
2607
2608 `Locked` is a list of extension IDs that the user cannot disable or uninstall.

2682 ### ExtensionSettings
2683 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.
2684
2685 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.
2686
2687 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).
2688
2689 The configuration for each extension is another dictionary that can contain the fields documented below.
2690
2691 | Name | Description |
2692 | --- | --- |
2693 | `installation_mode` | Maps to a string indicating the installation mode for the extension. The valid strings are `allowed`,`blocked`,`force_installed`, and `normal_installed`.
2694 | &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.
2695 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`blocked`| Blocks installation of the extension and removes it from the device if already installed.
2696 | &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.
2697 | &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.
2698 | `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.
2699 | `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.
2700 | `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.
2701 | `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.
2702 | `restricted_domains` | An array of domains on which content scripts can't be run. This setting can be used only for the default configuration.
2703 | `updates_disabled` | (Firefox 89, Firefox ESR 78.11) Boolean that indicates whether or not to disable automatic updates for an individual extension.

3002 ### GoToIntranetSiteForSingleWordEntryInAddressBar
3003 Whether to always go through the DNS server before sending a single word search string to a search engine.
3004
3005 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.
3006
3007 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.
3008
3009 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.
3010
3011 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`.
3012
3013 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`.

3047 ### Handlers
3048 Configure default application handlers. This policy is based on the internal format of `handlers.json`.
3049
3050 You can configure handlers based on a mime type (`mimeTypes`), a file's extension (`extensions`), or a protocol (`schemes`).
3051
3052 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.
3053
3054 | Name | Description |
3055 | --- | --- |
3056 | `action`| Can be either `saveToDisk`, `useHelperApp`, `useSystemDefault`.
3057 | `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.
3058 | `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.
3059 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`name` | The display name of the handler (might not be used).
3060 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`path`| The native path to the executable to be used.
3061 | &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.

3721 ### ManualAppUpdateOnly
3722
3723 Switch to manual updates only.
3724
3725 If this policy is enabled:
3726  1. The user will never be prompted to install updates
3727  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.
3728  3. The update UI will work as expected, unlike when using DisableAppUpdate.
3729
3730 This policy is primarily intended for advanced end users, not for enterprises.

4078
4079 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.

4123 ### Permissions
4124 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.
4125
4126 `Allow` is a list of origins where the feature is allowed.
4127
4128 `Block` is a list of origins where the feature is not allowed.
4129
4130 `BlockNewRequests` determines whether or not new requests can be made for the feature.
4131
4132 `Locked` prevents the user from changing preferences for the feature.
4133
4134 `Default` specifies the default value for Autoplay. block-audio-video is not supported on Firefox ESR 68.
4135
4136 **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)\

4525 ### Preferences
4526 Set and lock preferences.
4527
4528 **NOTE** On Windows, in order to use this policy, you must clear all settings in the old **Preferences (Deprecated)** section.
4529
4530 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.
4531
4532 Preferences that start with the following prefixes are supported:
4533 ```
4534 accessibility.
4535 app.update.* (Firefox 86, Firefox 78.8)
4536 browser.
4537 datareporting.policy.
4538 dom.
4539 extensions.
4540 general.autoScroll (Firefox 83, Firefox ESR 78.5)
4541 general.smoothScroll (Firefox 83, Firefox ESR 78.5)
4542 geo.
4543 gfx.
4544 intl.
4545 keyword.enabled (Firefox 95, Firefox ESR 91.4)
4546 layers.
4547 layout.
4548 media.
4549 network.
4550 pdfjs. (Firefox 84, Firefox ESR 78.6)
4551 places.
4552 print.
4553 signon. (Firefox 83, Firefox ESR 78.5)
4554 spellchecker. (Firefox 84, Firefox ESR 78.6)
4555 toolkit.legacyUserProfileCustomizations.stylesheets (Firefox 95, Firefox ESR 91.4)
4556 ui.
4557 widget.
4558 ```
4559 as well as the following security preferences:
4560 | Preference | Type | Default
4561 | --- | --- | ---
4562 | security.default_personal_cert | string | Ask Every Time
4563 | &nbsp;&nbsp;&nbsp;&nbsp;If set to Select Automatically, Firefox automatically chooses the default personal certificate.
4564 | security.insecure_connection_text.enabled | bool | false
4565 | &nbsp;&nbsp;&nbsp;&nbsp;If set to true, adds the words "Not Secure" for insecure sites.
4566 | security.insecure_connection_text.pbmode.enabled | bool | false
4567 | &nbsp;&nbsp;&nbsp;&nbsp;If set to true, adds the words "Not Secure" for insecure sites in private browsing.
4568 | security.insecure_field_warning.contextual.enabled | bool | true
4569 | &nbsp;&nbsp;&nbsp;&nbsp;If set to false, remove the warning for inscure login fields.
4570 | security.mixed_content.block_active_content | boolean | true
4571 | &nbsp;&nbsp;&nbsp;&nbsp;If false, mixed active content (HTTP and HTTPS) is not blocked.
4572 | security.osclientcerts.autoload | boolean | false
4573 | &nbsp;&nbsp;&nbsp;&nbsp;If true, client certificates are loaded from the operating system certificate store.
4574 | security.ssl.errorReporting.enabled | boolean | true
4575 | &nbsp;&nbsp;&nbsp;&nbsp;If false, SSL errors cannot be sent to Mozilla.
4576 | security.tls.enable_0rtt_data | boolean | true
4577 | &nbsp;&nbsp;&nbsp;&nbsp;If false, TLS early data is turned off (Firefox 93, Firefox 91.2, Firefox 78.15).
4578 | security.tls.hello_downgrade_check | boolean | true
4579 | &nbsp;&nbsp;&nbsp;&nbsp;If false, the TLS 1.3 downgrade check is disabled.
4580 | security.tls.version.enable-deprecated | boolean | false
4581 | &nbsp;&nbsp;&nbsp;&nbsp;If true, browser will accept TLS 1.0. and TLS 1.1 (Firefox 86, Firefox 78.8).
4582 | security.warn_submit_secure_to_insecure | boolean | true
4583 | &nbsp;&nbsp;&nbsp;&nbsp;If false, no warning is shown when submitting a form from https to http.
4584 &nbsp;
4585
4586 Using the preference as the key, set the `Value` to the corresponding preference value.
4587
4588 `Status` can be "default", "locked", "user" or "clear"
4589
4590 * `"default"`: Read/Write: Settings appear as default even if factory default differs.
4591 * `"locked"`: Read-Only: Settings appear as default even if factory default differs.
4592 * `"user"`: Read/Write: Settings appear as changed if it differs from factory default.
4593 * `"clear"`: Read/Write: `Value` has no effect. Resets to factory defaults on each startup.
4594
4595 `"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```.
4596
4597 `"user"` preferences persist even if the policy is removed, so if you need to remove them, you should use the clear policy.
4598
4599 See the examples below for more detail.
4600
4601 IMPORTANT: Make sure you're only setting a particular preference using this mechanism and not some other way.
