1 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`.

3 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:
4
5 ```
6 {
7 "policies": {
8 "Authentication": {
9 "SPNEGO": ["mydomain.com", "https://myotherdomain.com"]
10 }
11 "Authentication_Comment": "These domains are required for us"
12 }
13 }

488 ### AutoLaunchProtocolsFromOrigins
489 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.
490
491 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.
492
493 The schema is:
494 ```
495 {
496 "items": {
497 "properties": {
498 "allowed_origins": {
499 "items": {
500 "type": "string"

580 ### BackgroundAppUpdate
581
582 Enable or disable **automatic** application update **in the background**, when the application is not running.
583
584 If set to true, application updates may be installed (without user approval) in the background, even when the application is not running. The operating system might still require approval.
585
586 If set to false, the application will not try to install updates when the application is not running.
587
588 If you have disabled updates via `DisableAppUpdate` or disabled automatic updates via `AppAutoUpdate`, this policy has no effect.
589
590 If you are having trouble getting the background task to run, verify your configuration with the ["Requirements to run" section in this support document](https://support.mozilla.org/en-US/kb/enable-background-updates-firefox-windows).

770 Note: [`ManagedBookmarks`](#managedbookmarks) is the new recommended way to add bookmarks. This policy will continue to be supported.
771
772 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.
773
774 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.

888 ### Certificates
889
890 ### Certificates | ImportEnterpriseRoots
891
892 Trust certificates that have been added to the operating system certificate store by a user or administrator.
893
894 Note: This policy only works on Windows and macOS. For Linux discussion, see [bug 1600509](https://bugzilla.mozilla.org/show_bug.cgi?id=1600509).
895

935 ### Certificates | Install
936
937 Install certificates into the Firefox certificate store. If only a filename is specified, Firefox searches for the file in the following locations:
938
939 - Windows
940 - %USERPROFILE%\AppData\Local\Mozilla\Certificates
941 - %USERPROFILE%\AppData\Roaming\Mozilla\Certificates
942 - macOS
943 - /Library/Application Support/Mozilla/Certificates
944 - ~/Library/Application Support/Mozilla/Certificates
945 - Linux
946 - /usr/lib/mozilla/certificates
947 - /usr/lib64/mozilla/certificates
948 - ~/.mozilla/certificates
949
950 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.
951
952 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.
953
954 Certificates are installed using the trust string `CT,CT,`.
955
956 Binary (DER) and ASCII (PEM) certificates are both supported.

2434 ### EnableTrackingProtection
2435 Configure tracking protection.
2436
2437 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.
2438
2439 If `Value` is set to false, tracking protection is disabled and locked in both the regular browser and private browsing.
2440
2441 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.
2442
2443 If `Cryptomining` is set to true, cryptomining scripts on websites are blocked.
2444
2445 If `Fingerprinting` is set to true, fingerprinting scripts on websites are blocked.
2446
2447 If `EmailTracking` is set to true, hidden email tracking pixels and scripts on websites are blocked. (Firefox 112)
2448
2449 `Exceptions` are origins for which tracking protection is not enabled.
2450

2606 This policy is based on the [Chrome policy](https://chromeenterprise.google/policies/#ExemptDomainFileTypePairsFromFileTypeDownloadWarnings) of the same name.
2607
2608 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.

2668 ### Extensions
2669 Control the installation, uninstallation and locking of extensions.
2670
2671 We strongly recommend 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.
2672
2673 This method will be deprecated in the near future.
2674
2675 `Install` is a list of URLs or native paths for extensions to be installed.
2676
2677 `Uninstall` is a list of extension IDs that should be uninstalled if found.
2678
2679 `Locked` is a list of extension IDs that the user cannot disable or uninstall.

2753 ### ExtensionSettings
2754 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.
2755
2756 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.
2757
2758 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).
2759
2760 The configuration for each extension is another dictionary that can contain the fields documented below.
2761
2762 | Name | Description |
2763 | --- | --- |
2764 | `installation_mode` | Maps to a string indicating the installation mode for the extension. The valid strings are `allowed`,`blocked`,`force_installed`, and `normal_installed`.
2765 | &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.
2766 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`blocked`| Blocks installation of the extension and removes it from the device if already installed.
2767 | &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.
2768 | &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.
2769 | `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.
2770 | `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.
2771 | `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.
2772 | `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.
2773 | `restricted_domains` | An array of domains on which content scripts can't be run. This setting can be used only for the default configuration.
2774 | `updates_disabled` | (Firefox 89, Firefox ESR 78.11) Boolean that indicates whether or not to disable automatic updates for an individual extension.
2775 | `default_area` | (Firefox 113) String that indicates where to place the extension icon by default. Possible values are `navbar` and `menupanel`.
2776

3069 ### GoToIntranetSiteForSingleWordEntryInAddressBar
3070 Whether to always go through the DNS server before sending a single word search string to a search engine.
3071
3072 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.
3073
3074 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.
3075
3076 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.
3077
3078 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`.
3079
3080 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`.
3081

3083 **CCK2 Equivalent:** `N/A`\

3114 ### Handlers
3115 Configure default application handlers. This policy is based on the internal format of `handlers.json`.
3116
3117 You can configure handlers based on a mime type (`mimeTypes`), a file's extension (`extensions`), or a protocol (`schemes`).
3118
3119 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.
3120
3121 | Name | Description |
3122 | --- | --- |
3123 | `action`| Can be either `saveToDisk`, `useHelperApp`, `useSystemDefault`.
3124 | `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.
3125 | `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.
3126 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`name` | The display name of the handler (might not be used).
3127 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`path`| The native path to the executable to be used.
3128 | &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.

3794 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.
3795 3. The update UI will work as expected, unlike when using DisableAppUpdate.
3796

4140 Disable or configure PDF.js, the built-in PDF viewer.
4141
4142 If `Enabled` is set to false, the built-in PDF viewer is disabled.
4143
4144 If `EnablePermissions` is set to true, the built-in PDF viewer will honor document permissions like preventing the copying of text.
4145
4146 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.

4190 ### Permissions
4191 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.
4192
4193 `Allow` is a list of origins where the feature is allowed.
4194
4195 `Block` is a list of origins where the feature is not allowed.
4196
4197 `BlockNewRequests` determines whether or not new requests can be made for the feature.
4198
4199 `Locked` prevents the user from changing preferences for the feature.
4200
4201 `Default` specifies the default value for Autoplay. block-audio-video is not supported on Firefox ESR 68.
4202
4203 **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)\
4204 **CCK2 Equivalent:** N/A\
4205 **Preferences Affected:** `permissions.default.camera`, `permissions.default.microphone`, `permissions.default.geo`, `permissions.default.desktop-notification`, `media.autoplay.default`, `permissions.default.xr`

4667 | &nbsp;&nbsp;&nbsp;&nbsp;If false, no warning is shown when submitting a form from https to http.
4668
4669 Using the preference as the key, set the `Value` to the corresponding preference value.
4670
4671 `Status` can be "default", "locked", "user" or "clear"
4672
4673 * `"default"`: Read/Write: Settings appear as default even if factory default differs.
4674 * `"locked"`: Read-Only: Settings appear as default even if factory default differs.
4675 * `"user"`: Read/Write: Settings appear as changed if it differs from factory default.
4676 * `"clear"`: Read/Write: `Value` has no effect. Resets to factory defaults on each startup.
4677
4678 `"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```.
4679
4680 `"user"` preferences persist even if the policy is removed, so if you need to remove them, you should use the clear policy.
4681
4682 You can also set the `Type` starting in Firefox 123 and Firefox ESR 115.8. It can be `number`, `boolean` or `string`. This is especially useful if you are seeing 0 or 1 values being converted to booleans when set as user preferences.
4683
4684 See the examples below for more detail.
4685
4686 IMPORTANT: Make sure you're only setting a particular preference using this mechanism and not some other way.

5179 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.
