   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`.

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

 758 ### Bookmarks
 759
 760 Note: [`ManagedBookmarks`](#managedbookmarks) is the new recommended way to add bookmarks. This policy will continue to be supported.
 761
 762 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.
 763
 764 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.

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

1010 | reject-tracker-and-partition-foreign | Reject cookies for known trackers and partition third-party cookies (Total Cookie Protection) (default for private browsing)
1011
1012 `Default` (Deprecated) determines whether cookies are accepted at all.
1013
1014 `AcceptThirdParty` (Deprecated) determines how third-party cookies are handled.
1015
1016 `ExpireAtSessionEnd` determines when cookies expire.
1017
1018 `RejectTracker` (Deprecated) only rejects cookies for trackers.
1019
1020 `Locked` prevents the user from changing cookie preferences.

2394
2395 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.
2396
2397 If `Value` is set to false, tracking protection is disabled and locked in both the regular browser and private browsing.
2398
2399 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.
2400
2401 If `Cryptomining` is set to true, cryptomining scripts on websites are blocked.
2402
2403 If `Fingerprinting` is set to true, fingerprinting scripts on websites are blocked.
2404
2405 `Exceptions` are origins for which tracking protection is not enabled.

2561
2562 This policy is based on the [Chrome policy](https://chromeenterprise.google/policies/#ExemptDomainFileTypePairsFromFileTypeDownloadWarnings) of the same name.
2563
2564 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.

2624 ### Extensions
2625 Control the installation, uninstallation and locking of extensions.
2626
2627 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.
2628
2629 `Install` is a list of URLs or native paths for extensions to be installed.
2630
2631 `Uninstall` is a list of extension IDs that should be uninstalled if found.
2632
2633 `Locked` is a list of extension IDs that the user cannot disable or uninstall.

2707 ### ExtensionSettings
2708 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.
2709
2710 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.
2711
2712 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).
2713
2714 The configuration for each extension is another dictionary that can contain the fields documented below.
2715
2716 | Name | Description |
2717 | --- | --- |
2718 | `installation_mode` | Maps to a string indicating the installation mode for the extension. The valid strings are `allowed`,`blocked`,`force_installed`, and `normal_installed`.
2719 | &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.
2720 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`blocked`| Blocks installation of the extension and removes it from the device if already installed.
2721 | &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.
2722 | &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.
2723 | `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.
2724 | `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.
2725 | `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.
2726 | `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.
2727 | `restricted_domains` | An array of domains on which content scripts can't be run. This setting can be used only for the default configuration.
2728 | `updates_disabled` | (Firefox 89, Firefox ESR 78.11) Boolean that indicates whether or not to disable automatic updates for an individual extension.

3027 ### GoToIntranetSiteForSingleWordEntryInAddressBar
3028 Whether to always go through the DNS server before sending a single word search string to a search engine.
3029
3030 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.
3031
3032 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.
3033
3034 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.
3035
3036 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`.
3037
3038 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`.

3072 ### Handlers
3073 Configure default application handlers. This policy is based on the internal format of `handlers.json`.
3074
3075 You can configure handlers based on a mime type (`mimeTypes`), a file's extension (`extensions`), or a protocol (`schemes`).
3076
3077 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.
3078
3079 | Name | Description |
3080 | --- | --- |
3081 | `action`| Can be either `saveToDisk`, `useHelperApp`, `useSystemDefault`.
3082 | `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.
3083 | `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.
3084 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`name` | The display name of the handler (might not be used).
3085 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`path`| The native path to the executable to be used.
3086 | &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.

3746 ### ManualAppUpdateOnly
3747
3748 Switch to manual updates only.
3749
3750 If this policy is enabled:
3751  1. The user will never be prompted to install updates
3752  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.
3753  3. The update UI will work as expected, unlike when using DisableAppUpdate.
3754
3755 This policy is primarily intended for advanced end users, not for enterprises.

4103
4104 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.

4148 ### Permissions
4149 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.
4150
4151 `Allow` is a list of origins where the feature is allowed.
4152
4153 `Block` is a list of origins where the feature is not allowed.
4154
4155 `BlockNewRequests` determines whether or not new requests can be made for the feature.
4156
4157 `Locked` prevents the user from changing preferences for the feature.
4158
4159 `Default` specifies the default value for Autoplay. block-audio-video is not supported on Firefox ESR 68.
4160
4161 **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)\

4550 ### Preferences
4551 Set and lock preferences.
4552
4553 **NOTE** On Windows, in order to use this policy, you must clear all settings in the old **Preferences (Deprecated)** section.
4554
4555 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.
4556
4557 Preferences that start with the following prefixes are supported:
4558 ```
4559 accessibility.
4560 app.update.* (Firefox 86, Firefox 78.8)
4561 browser.
4562 datareporting.policy.
4563 dom.
4564 extensions.
4565 general.autoScroll (Firefox 83, Firefox ESR 78.5)
4566 general.smoothScroll (Firefox 83, Firefox ESR 78.5)
4567 geo.
4568 gfx.
4569 intl.
4570 keyword.enabled (Firefox 95, Firefox ESR 91.4)
4571 layers.
4572 layout.
4573 media.
4574 network.
4575 pdfjs. (Firefox 84, Firefox ESR 78.6)
4576 places.
4577 print.
4578 signon. (Firefox 83, Firefox ESR 78.5)
4579 spellchecker. (Firefox 84, Firefox ESR 78.6)
4580 toolkit.legacyUserProfileCustomizations.stylesheets (Firefox 95, Firefox ESR 91.4)
4581 ui.
4582 widget.
4583 ```
4584 as well as the following security preferences:
4585 | Preference | Type | Default
4586 | --- | --- | ---
4587 | security.default_personal_cert | string | Ask Every Time
4588 | &nbsp;&nbsp;&nbsp;&nbsp;If set to Select Automatically, Firefox automatically chooses the default personal certificate.
4589 | security.insecure_connection_text.enabled | bool | false
4590 | &nbsp;&nbsp;&nbsp;&nbsp;If set to true, adds the words "Not Secure" for insecure sites.
4591 | security.insecure_connection_text.pbmode.enabled | bool | false
4592 | &nbsp;&nbsp;&nbsp;&nbsp;If set to true, adds the words "Not Secure" for insecure sites in private browsing.
4593 | security.insecure_field_warning.contextual.enabled | bool | true
4594 | &nbsp;&nbsp;&nbsp;&nbsp;If set to false, remove the warning for inscure login fields.
4595 | security.mixed_content.block_active_content | boolean | true
4596 | &nbsp;&nbsp;&nbsp;&nbsp;If false, mixed active content (HTTP and HTTPS) is not blocked.
4597 | security.osclientcerts.autoload | boolean | false
4598 | &nbsp;&nbsp;&nbsp;&nbsp;If true, client certificates are loaded from the operating system certificate store.
4599 | security.ssl.errorReporting.enabled | boolean | true
4600 | &nbsp;&nbsp;&nbsp;&nbsp;If false, SSL errors cannot be sent to Mozilla.
4601 | security.tls.enable_0rtt_data | boolean | true
4602 | &nbsp;&nbsp;&nbsp;&nbsp;If false, TLS early data is turned off (Firefox 93, Firefox 91.2, Firefox 78.15).
4603 | security.tls.hello_downgrade_check | boolean | true
4604 | &nbsp;&nbsp;&nbsp;&nbsp;If false, the TLS 1.3 downgrade check is disabled.
4605 | security.tls.version.enable-deprecated | boolean | false
4606 | &nbsp;&nbsp;&nbsp;&nbsp;If true, browser will accept TLS 1.0. and TLS 1.1 (Firefox 86, Firefox 78.8).
4607 | security.warn_submit_secure_to_insecure | boolean | true
4608 | &nbsp;&nbsp;&nbsp;&nbsp;If false, no warning is shown when submitting a form from https to http.
4609 &nbsp;
4610
4611 Using the preference as the key, set the `Value` to the corresponding preference value.
4612
4613 `Status` can be "default", "locked", "user" or "clear"
4614
4615 * `"default"`: Read/Write: Settings appear as default even if factory default differs.
4616 * `"locked"`: Read-Only: Settings appear as default even if factory default differs.
4617 * `"user"`: Read/Write: Settings appear as changed if it differs from factory default.
4618 * `"clear"`: Read/Write: `Value` has no effect. Resets to factory defaults on each startup.
4619
4620 `"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```.
4621
4622 `"user"` preferences persist even if the policy is removed, so if you need to remove them, you should use the clear policy.
4623
4624 See the examples below for more detail.
4625
4626 IMPORTANT: Make sure you're only setting a particular preference using this mechanism and not some other way.
