   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   "policies": {
   7     "Authentication": {
   8       "SPNEGO": ["mydomain.com", "https://myotherdomain.com"]
   9     }
  10     "Authentication_Comment": "These domains are required for us"
  11   }
  12 }
  13 ```
  14 Note: The `policies.json` must use the UTF-8 encoding.

 609 ### AutoLaunchProtocolsFromOrigins
 610 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.
 611
 612 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.
 613
 614 The schema is:
 615 ```
 616 {
 617  "items": {
 618   "properties": {
 619    "allowed_origins": {
 620     "items": {
 621      "type": "string"

 713 ### BackgroundAppUpdate
 714
 715 Enable or disable **automatic** application update **in the background**, when the application is not running.
 716
 717 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.
 718
 719 If set to false, the application will not try to install updates when the application is not running.
 720
 721 If you have disabled updates via `DisableAppUpdate` or disabled automatic updates via `AppAutoUpdate`, this policy has no effect.
 722
 723 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).

 901 ### Bookmarks
 902
 903 Note: [`ManagedBookmarks`](#managedbookmarks) is the new recommended way to add bookmarks. This policy will continue to be supported.
 904
 905 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.
 906
 907 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.

1080 ### Certificates | Install
1081
1082 Install certificates into the Firefox certificate store. If only a filename is specified, Firefox searches for the file in the following locations:
1083
1084 - Windows
1085   - %USERPROFILE%\AppData\Local\Mozilla\Certificates
1086   - %USERPROFILE%\AppData\Roaming\Mozilla\Certificates
1087 - macOS
1088   - /Library/Application Support/Mozilla/Certificates
1089   - ~/Library/Application Support/Mozilla/Certificates
1090 - Linux
1091   - /usr/lib/mozilla/certificates
1092   - /usr/lib64/mozilla/certificates
1093   - ~/.mozilla/certificates
1094
1095 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.
1096
1097 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.
1098
1099 Certificates are installed using the trust string `CT,CT,`.
1100
1101 Binary (DER) and ASCII (PEM) certificates are both supported.

1146 Set policies related to [containers](https://addons.mozilla.org/firefox/addon/multi-account-containers/).
1147
1148 Currently you can set the initial set of containers.
1149
1150 For each container, you can specify the name, icon, and color.
1151
1152 | Name | Description |
1153 | --- | --- |
1154 | `name`| Name of container
1155 | `icon` | Can be `fingerprint`, `briefcase`, `dollar`, `cart`, `vacation`, `gift`, `food`, `fruit`, `pet`, `tree`, `chill`, `circle`, `fence`
1156 | `color` | Can be `blue`, `turquoise`, `green`, `yellow`, `orange`, `red`, `pink`, `purple`, `toolbar`

1242 ### ContentAnalysis
1243 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).
1244
1245 `AgentName` is the name of the DLP agent. This is used in dialogs and notifications about DLP operations. The default is "A DLP Agent".
1246
1247 `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.
1248
1249 `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&#124;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.
1250
1251 `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.
1252
1253 `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.
1254
1255 `DefaultResult` indicates the desired behavior for DLP requests if there is a problem connecting to the DLP agent. The default is 0.
1256
1257 | Value | Description
1258 | --- | --- |
1259 | 0 | Deny the request (default)
1260 | 1 | Warn the user and allow them to choose whether to allow or deny
1261 | 2 | Allow the request
1262
1263 `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.
1264
1265 `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.
1266
1267 `IsPerUser` indicates whether the pipe the DLP agent has created is per-user or per-system. The default is true, meaning per-user.
1268
1269 `PipePathName` is the name of the pipe the DLP agent has created and Firefox will connect to. The default is "path_user".
1270
1271 `ShowBlockedResult` indicates whether Firefox should show a notification when a DLP request is denied. The default is true.
1272
1273 **Compatibility:** Firefox 130\
1274 **CCK2 Equivalent:** N/A\
1275 **Preferences Affected:** `browser.contentanalysis.agent_name`, `browser.contentanalysis.agent_timeout`, `browser.contentanalysis.allow_url_regex_list`, `browser.contentanalysis.bypass_for_same_tab_operations`, `browser.contentanalysis.client_signature`, `browser.contentanalysis.default_result`, `browser.contentanalysis.deny_url_regex_list`, `browser.contentanalysis.enabled`, `browser.contentanalysis.is_per_user`, `browser.contentanalysis.pipe_path_name`, `browser.contentanalysis.show_blocked_result`

2753 ### EnableTrackingProtection
2754 Configure tracking protection.
2755
2756 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.
2757
2758 If `Value` is set to false, tracking protection is disabled and locked in both the regular browser and private browsing.
2759
2760 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.
2761
2762 If `Cryptomining` is set to true, cryptomining scripts on websites are blocked.
2763
2764 If `Fingerprinting` is set to true, fingerprinting scripts on websites are blocked.
2765
2766 If `EmailTracking` is set to true, hidden email tracking pixels and scripts on websites are blocked. (Firefox 112)
2767
2768 `Exceptions` are origins for which tracking protection is not enabled.

2859 Enable or disable Encrypted Media Extensions and optionally lock it.
2860
2861 If `Enabled` is set to false, encrypted media extensions (like Widevine) are not downloaded by Firefox unless the user consents to installing them.
2862

2925 This policy is based on the [Chrome policy](https://chromeenterprise.google/policies/#ExemptDomainFileTypePairsFromFileTypeDownloadWarnings) of the same name.
2926

2999 ### Extensions
3000 Control the installation, uninstallation and locking of extensions.
3001
3002 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.
3003
3004 This method will be deprecated in the near future.
3005
3006 `Install` is a list of URLs or native paths for extensions to be installed.
3007
3008 `Uninstall` is a list of extension IDs that should be uninstalled if found.
3009
3010 `Locked` is a list of extension IDs that the user cannot disable or uninstall.

3084 ### ExtensionSettings
3085 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.
3086
3087 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.
3088
3089 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).
3090
3091 The configuration for each extension is another dictionary that can contain the fields documented below.
3092
3093 | Name | Description |
3094 | --- | --- |
3095 | `installation_mode` | Maps to a string indicating the installation mode for the extension. The valid strings are `allowed`,`blocked`,`force_installed`, and `normal_installed`.
3096 | &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.
3097 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`blocked`| Blocks installation of the extension and removes it from the device if already installed.
3098 | &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.
3099 | &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.
3100 | `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.
3101 | `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.
3102 | `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.
3103 | `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.
3104 | `restricted_domains` | An array of domains on which content scripts can't be run. This setting can be used only for the default configuration.
3105 | `updates_disabled` | (Firefox 89, Firefox ESR 78.11) Boolean that indicates whether or not to disable automatic updates for an individual extension.
3106 | `default_area` | (Firefox 113) String that indicates where to place the extension icon by default. Possible values are `navbar` and `menupanel`.
3107 | `temporarily_allow_weak_signatures`| (Firefox 127) A boolean that indicates whether to allow installing extensions signed using deprecated signature algorithms.
3108
3109 **Compatibility:** Firefox 69, Firefox ESR 68.1 (As of Firefox 85, Firefox ESR 78.7, installing a theme makes it the default.)\

3418 ### GoToIntranetSiteForSingleWordEntryInAddressBar
3419 Whether to always go through the DNS server before sending a single word search string to a search engine.
3420
3421 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.
3422
3423 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.
3424
3425 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.
3426
3427 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`.
3428
3429 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`.

3463 ### Handlers
3464 Configure default application handlers. This policy is based on the internal format of `handlers.json`.
3465
3466 You can configure handlers based on a mime type (`mimeTypes`), a file's extension (`extensions`), or a protocol (`schemes`).
3467
3468 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.
3469
3470 | Name | Description |
3471 | --- | --- |
3472 | `action`| Can be either `saveToDisk`, `useHelperApp`, `useSystemDefault`.
3473 | `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.
3474 | `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.
3475 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`name` | The display name of the handler (might not be used).
3476 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`path`| The native path to the executable to be used.
3477 | &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.

4247 ### ManualAppUpdateOnly
4248
4249 Switch to manual updates only.
4250
4251 If this policy is enabled:
4252  1. The user will never be prompted to install updates
4253  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.
4254  3. The update UI will work as expected, unlike when using DisableAppUpdate.
4255
4256 This policy is primarily intended for advanced end users, not for enterprises, but it is available via GPO.

4623
4624 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.

4668 ### Permissions
4669 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.
4670
4671 `Allow` is a list of origins where the feature is allowed.
4672
4673 `Block` is a list of origins where the feature is not allowed.
4674
4675 `BlockNewRequests` determines whether or not new requests can be made for the feature.
4676
4677 `Locked` prevents the user from changing preferences for the feature.
4678
4679 `Default` specifies the default value for Autoplay. block-audio-video is not supported on Firefox ESR 68.
4680
4681 **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)\

5280 Using the preference as the key, set the `Value` to the corresponding preference value.
5281
5282 `Status` can be "default", "locked", "user" or "clear"
5283
5284 * `"default"`: Read/Write: Settings appear as default even if factory default differs.
5285 * `"locked"`: Read-Only: Settings appear as default even if factory default differs.
5286 * `"user"`: Read/Write: Settings appear as changed if it differs from factory default.
5287 * `"clear"`: Read/Write: `Value` has no effect. Resets to factory defaults on each startup.
5288
5289 `"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```.
5290
5291 `"user"` preferences persist even if the policy is removed, so if you need to remove them, you should use the clear policy.
5292
5293 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.
5294
5295 See the examples below for more detail.
5296
5297 IMPORTANT: Make sure you're only setting a particular preference using this mechanism and not some other way.

5527 Unless you lock this policy, changes the user already has in place will take effect.
5528
5529 `Mode` is the proxy method being used.
5530
5531 `Locked` is whether or not proxy settings can be changed.
5532

5545 `Passthrough` is list of hostnames or IP addresses that will not be proxied. Use `<local>` to bypass proxying for all hostnames which do not contain periods.
5546
5547 `AutoConfigURL` is a  URL for proxy configuration (only used if Mode is autoConfig).
5548
5549 `AutoLogin` means do not prompt for authentication if password is saved.
5550
