   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 }
  14 ```

 526 ### AutoLaunchProtocolsFromOrigins
 527 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.
 528
 529 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.
 530
 531 The schema is:
 532 ```
 533 {
 534  "items": {
 535   "properties": {
 536    "allowed_origins": {
 537     "items": {

 618 ### BackgroundAppUpdate
 619
 620 Enable or disable **automatic** application update **in the background**, when the application is not running.
 621
 622 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.
 623
 624 If set to false, the application will not try to install updates when the application is not running.
 625
 626 If you have disabled updates via `DisableAppUpdate` or disabled automatic updates via `AppAutoUpdate`, this policy has no effect.
 627
 628 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).

 807
 808 Note: [`ManagedBookmarks`](#managedbookmarks) is the new recommended way to add bookmarks. This policy will continue to be supported.
 809
 810 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.
 811
 812 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.

 927
 928 ### Certificates | ImportEnterpriseRoots
 929
 930 Trust certificates that have been added to the operating system certificate store by a user or administrator.
 931
 932 Note: This policy only works on Windows and macOS. For Linux discussion, see [bug 1600509](https://bugzilla.mozilla.org/show_bug.cgi?id=1600509).

 973 ### Certificates | Install
 974
 975 Install certificates into the Firefox certificate store. If only a filename is specified, Firefox searches for the file in the following locations:
 976
 977 - Windows
 978   - %USERPROFILE%\AppData\Local\Mozilla\Certificates
 979   - %USERPROFILE%\AppData\Roaming\Mozilla\Certificates
 980 - macOS
 981   - /Library/Application Support/Mozilla/Certificates
 982   - ~/Library/Application Support/Mozilla/Certificates
 983 - Linux
 984   - /usr/lib/mozilla/certificates
 985   - /usr/lib64/mozilla/certificates
 986   - ~/.mozilla/certificates
 987
 988 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.
 989
 990 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.
 991
 992 Certificates are installed using the trust string `CT,CT,`.
 993
 994 Binary (DER) and ASCII (PEM) certificates are both supported.

1123 ### ContentAnalysis
1124 Configure Firefox to use an agent for Data Loss Prevention (DLP) that is compatible with the [Google Chrome Content Analysis Connector Agent SDK](https://github.com/chromium/content_analysis_sdk).
1125
1126 `AgentName` is the name of the DLP agent. This is used in dialogs and notifications about DLP operations. The default is "A DLP Agent".
1127
1128 `AgentTimeout` is the timeout in number of seconds after a DLP request is sent to the agent. After this timeout, the request will be denied unless `DefaultResult` is set to 1 or 2. The default is 30.
1129
1130 `AllowUrlRegexList` is a space-separated list of regular expressions that indicates URLs for which DLP operations will always be allowed without consulting the agent. The default is "^about:(?!blank|srcdoc).*", meaning that any pages that start with "about:" will be exempt from DLP except for "about:blank" and "about:srcdoc", as these can be controlled by web content.
1131
1132 `BypassForSameTabOperations` indicates whether Firefox will automatically allow DLP requests whose data comes from the same tab and frame - for example, if data is copied to the clipboard and then pasted on the same page. The default is false.
1133
1134 `ClientSignature` indicates the required signature of the DLP agent connected to the pipe. If this is a non-empty string and the DLP agent does not have a signature with a Subject Name that exactly matches this value, Firefox will not connect to the pipe. The default is the empty string.
1135
1136 `DefaultResult` indicates the desired behavior for DLP requests if there is a problem connecting to the DLP agent. The default is 0.
1137
1138 | Value | Description
1139 | --- | --- |
1140 | 0 | Deny the request (default)
1141 | 1 | Warn the user and allow them to choose whether to allow or deny
1142 | 2 | Allow the request
1143
1144 `DenyUrlRegexList` is a space-separated list of regular expressions that indicates URLs for which DLP operations will always be denied without consulting the agent. The default is the empty string.
1145
1146 `Enabled` indicates whether Firefox should use DLP. Note that if this value is true and no DLP agent is running, all DLP requests will be denied unless `DefaultResult` is set to 1 or 2.
1147
1148 `IsPerUser` indicates whether the pipe the DLP agent has created is per-user or per-system. The default is true, meaning per-user.
1149
1150 `PipePathName` is the name of the pipe the DLP agent has created and Firefox will connect to. The default is "path_user".
1151
1152 `ShowBlockedResult` indicates whether Firefox should show a notification when a DLP request is denied. The default is true.

2745 ### EncryptedMediaExtensions
2746 Enable or disable Encrypted Media Extensions and optionally lock it.
2747
2748 If `Enabled` is set to false, encrypted media extensions (like Widevine) are not downloaded by Firefox unless the user consents to installing them.
2749
2750 If `Locked` is set to true and `Enabled` is set to false, Firefox will not download encrypted media extensions (like Widevine) or ask the user to install them.

2812 This policy is based on the [Chrome policy](https://chromeenterprise.google/policies/#ExemptDomainFileTypePairsFromFileTypeDownloadWarnings) of the same name.
2813
2814 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.

2874 ### Extensions
2875 Control the installation, uninstallation and locking of extensions.
2876
2877 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.
2878
2879 This method will be deprecated in the near future.
2880
2881 `Install` is a list of URLs or native paths for extensions to be installed.
2882
2883 `Uninstall` is a list of extension IDs that should be uninstalled if found.
2884
2885 `Locked` is a list of extension IDs that the user cannot disable or uninstall.

2959 ### ExtensionSettings
2960 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.
2961
2962 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.
2963
2964 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).
2965
2966 The configuration for each extension is another dictionary that can contain the fields documented below.
2967
2968 | Name | Description |
2969 | --- | --- |
2970 | `installation_mode` | Maps to a string indicating the installation mode for the extension. The valid strings are `allowed`,`blocked`,`force_installed`, and `normal_installed`.
2971 | &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.
2972 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`blocked`| Blocks installation of the extension and removes it from the device if already installed.
2973 | &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.
2974 | &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.
2975 | `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.
2976 | `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.
2977 | `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.
2978 | `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.
2979 | `restricted_domains` | An array of domains on which content scripts can't be run. This setting can be used only for the default configuration.
2980 | `updates_disabled` | (Firefox 89, Firefox ESR 78.11) Boolean that indicates whether or not to disable automatic updates for an individual extension.
2981 | `default_area` | (Firefox 113) String that indicates where to place the extension icon by default. Possible values are `navbar` and `menupanel`.

3280 ### GoToIntranetSiteForSingleWordEntryInAddressBar
3281 Whether to always go through the DNS server before sending a single word search string to a search engine.
3282
3283 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.
3284
3285 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.
3286
3287 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.
3288
3289 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`.
3290
3291 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`.

3325 ### Handlers
3326 Configure default application handlers. This policy is based on the internal format of `handlers.json`.
3327
3328 You can configure handlers based on a mime type (`mimeTypes`), a file's extension (`extensions`), or a protocol (`schemes`).
3329
3330 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.
3331
3332 | Name | Description |
3333 | --- | --- |
3334 | `action`| Can be either `saveToDisk`, `useHelperApp`, `useSystemDefault`.
3335 | `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.
3336 | `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.
3337 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`name` | The display name of the handler (might not be used).
3338 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`path`| The native path to the executable to be used.
3339 | &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.

3694 ### LegacyProfiles
3695 Disable the feature enforcing a separate profile for each installation.
3696
3697 If this policy set to true, Firefox will not try to create different profiles for installations of Firefox in different directories. This is the equivalent of the MOZ_LEGACY_PROFILES environment variable.
3698
3699 If this policy set to false, Firefox will create a new profile for each unique installation of Firefox.
3700

3999 ### ManualAppUpdateOnly
4000
4001 Switch to manual updates only.
4002
4003 If this policy is enabled:
4004  1. The user will never be prompted to install updates
4005  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.
4006  3. The update UI will work as expected, unlike when using DisableAppUpdate.
4007
4008 This policy is primarily intended for advanced end users, not for enterprises, but it is available via GPO.

4370 ### PDFjs
4371 Disable or configure PDF.js, the built-in PDF viewer.
4372
4373 If `Enabled` is set to false, the built-in PDF viewer is disabled.
4374
4375 If `EnablePermissions` is set to true, the built-in PDF viewer will honor document permissions like preventing the copying of text.
4376
4377 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.

4421 ### Permissions
4422 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.
4423
4424 `Allow` is a list of origins where the feature is allowed.
4425
4426 `Block` is a list of origins where the feature is not allowed.
4427
4428 `BlockNewRequests` determines whether or not new requests can be made for the feature.
4429
4430 `Locked` prevents the user from changing preferences for the feature.
4431
4432 `Default` specifies the default value for Autoplay. block-audio-video is not supported on Firefox ESR 68.
4433
4434 **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)\
4435 **CCK2 Equivalent:** N/A\
4436 **Preferences Affected:** `permissions.default.camera`, `permissions.default.microphone`, `permissions.default.geo`, `permissions.default.desktop-notification`, `media.autoplay.default`, `permissions.default.xr`

4747 ### PopupBlocking
4748 Configure the default pop-up window policy as well as origins for which pop-up windows are allowed.
4749
4750 `Allow` is a list of origins where popup-windows are allowed.
4751
4752 `Default` determines whether or not pop-up windows are allowed by default.
4753
4754 `Locked` prevents the user from changing pop-up preferences.

4823 ### Preferences
4824 Set and lock preferences.
4825
4826 **NOTE** On Windows, in order to use this policy, you must clear all settings in the old **Preferences (Deprecated)** section in group policy.
4827
4828 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.
4829
4830 Preferences that start with the following prefixes are supported:
4831 ```
4832 accessibility.
4833 alerts.* (Firefox 122, Firefox ESR 115.7)
4834 app.update.* (Firefox 86, Firefox ESR 78.8)

4862
4863 | Preference | Type | Default
4864 | --- | --- | --- |
4865 | security.default_personal_cert | string | Ask Every Time
4866 | &nbsp;&nbsp;&nbsp;&nbsp;If set to Select Automatically, Firefox automatically chooses the default personal certificate.
4867 | security.disable_button.openCertManager | string | N/A
4868 | &nbsp;&nbsp;&nbsp;&nbsp;If set to true and locked, the View Certificates button in preferences is disabled (Firefox 121, Firefox ESR 115.6)
4869 | security.disable_button.openDeviceManager | string | N/A
4870 | &nbsp;&nbsp;&nbsp;&nbsp;If set to true and locked, the Security Devices button in preferences is disabled (Firefox 121, Firefox ESR 115.6)
4871 | security.insecure_connection_text.enabled | bool | false
4872 | &nbsp;&nbsp;&nbsp;&nbsp;If set to true, adds the words "Not Secure" for insecure sites.
4873 | security.insecure_connection_text.pbmode.enabled | bool | false
4874 | &nbsp;&nbsp;&nbsp;&nbsp;If set to true, adds the words "Not Secure" for insecure sites in private browsing.
4875 | security.mixed_content.block_active_content | boolean | true
4876 | &nbsp;&nbsp;&nbsp;&nbsp;If false, mixed active content (HTTP and HTTPS) is not blocked.
4877 | security.osclientcerts.autoload | boolean | false
4878 | &nbsp;&nbsp;&nbsp;&nbsp;If true, client certificates are loaded from the operating system certificate store.
4879 | security.OCSP.enabled | integer | 1
4880 | &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.
4881 | security.OCSP.require | boolean | false
4882 | &nbsp;&nbsp;&nbsp;&nbsp; If true, if an OCSP request times out, the connection fails.
4883 | security.osclientcerts.assume_rsa_pss_support | boolean | true
4884 | &nbsp;&nbsp;&nbsp;&nbsp; If false, we don't assume an RSA key can do RSA-PSS. (Firefox 114, Firefox ESR 102.12)
4885 | security.ssl.enable_ocsp_stapling | boolean | true
4886 | &nbsp;&nbsp;&nbsp;&nbsp; If false, OCSP stapling is not enabled.
4887 | security.ssl.errorReporting.enabled | boolean | true
4888 | &nbsp;&nbsp;&nbsp;&nbsp;If false, SSL errors cannot be sent to Mozilla.
4889 | security.ssl.require_safe_negotiation | boolean | false
4890 | &nbsp;&nbsp;&nbsp;&nbsp;If true, Firefox will only negotiate TLS connections with servers that indicate they support secure renegotiation. (Firefox 118, Firefox ESR 115.3)
4891 | security.tls.enable_0rtt_data | boolean | true
4892 | &nbsp;&nbsp;&nbsp;&nbsp;If false, TLS early data is turned off. (Firefox 93, Firefox 91.2, Firefox 78.15)
4893 | security.tls.hello_downgrade_check | boolean | true
4894 | &nbsp;&nbsp;&nbsp;&nbsp;If false, the TLS 1.3 downgrade check is disabled.
4895 | security.tls.version.enable-deprecated | boolean | false
4896 | &nbsp;&nbsp;&nbsp;&nbsp;If true, browser will accept TLS 1.0. and TLS 1.1. (Firefox 86, Firefox 78.8)
4897 | security.warn_submit_secure_to_insecure | boolean | true
4898 | &nbsp;&nbsp;&nbsp;&nbsp;If false, no warning is shown when submitting a form from https to http.
4899
4900 Using the preference as the key, set the `Value` to the corresponding preference value.
4901
4902 `Status` can be "default", "locked", "user" or "clear"
4903
4904 * `"default"`: Read/Write: Settings appear as default even if factory default differs.
4905 * `"locked"`: Read-Only: Settings appear as default even if factory default differs.
4906 * `"user"`: Read/Write: Settings appear as changed if it differs from factory default.
4907 * `"clear"`: Read/Write: `Value` has no effect. Resets to factory defaults on each startup.
4908
4909 `"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```.
4910
4911 `"user"` preferences persist even if the policy is removed, so if you need to remove them, you should use the clear policy.
4912
4913 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.
4914
4915 See the examples below for more detail.
4916
4917 IMPORTANT: Make sure you're only setting a particular preference using this mechanism and not some other way.

5022 ### PrimaryPassword
5023 Require or prevent using a primary (formerly master) password.
5024
5025 If this value is true, a primary password is required. If this value is false, it works the same as if [`DisableMasterPasswordCreation`](#disablemasterpasswordcreation) was true and removes the primary password functionality.

5154
5155 `AutoConfigURL` is a  URL for proxy configuration (only used if Mode is autoConfig).
5156
5157 `AutoLogin` means do not prompt for authentication if password is saved.
