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

906 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.
908 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.

1040 Note: This policy only works on Windows and macOS. For Linux discussion, see [bug 1600509](https://bugzilla.mozilla.org/show_bug.cgi?id=1600509).
1042 See https://support.mozilla.org/kb/setting-certificate-authorities-firefox for more detail.

1076 "ImportEnterpriseRoots": true | false
1081 ### Certificates | Install
1083 Install certificates into the Firefox certificate store. If only a filename is specified, Firefox searches for the file in the following locations:
1086 - %USERPROFILE%\AppData\Local\Mozilla\Certificates
1087 - %USERPROFILE%\AppData\Roaming\Mozilla\Certificates
1089 - /Library/Application Support/Mozilla/Certificates
1090 - ~/Library/Application Support/Mozilla/Certificates
1092 - /usr/lib/mozilla/certificates
1093 - /usr/lib64/mozilla/certificates
1094 - ~/.mozilla/certificates
1096 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.
1098 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.
1100 Certificates are installed using the trust string `CT,CT,`.
1102 Binary (DER) and ASCII (PEM) certificates are both supported.

1244 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).
1246 `AgentName` is the name of the DLP agent. This is used in dialogs and notifications about DLP operations. The default is "A DLP Agent".
1248 `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.
1250 `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.
1252 `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.
1254 `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.
1256 `DefaultResult` indicates the desired behavior for DLP requests if there is a problem connecting to the DLP agent. The default is 0.
1258 | Value | Description
1260 | 0 | Deny the request (default)
1261 | 1 | Warn the user and allow them to choose whether to allow or deny
1262 | 2 | Allow the request
1264 `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.
1266 `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.
1268 `IsPerUser` indicates whether the pipe the DLP agent has created is per-user or per-system. The default is true, meaning per-user.
1270 `PipePathName` is the name of the pipe the DLP agent has created and Firefox will connect to. The default is "path_user".
1272 `ShowBlockedResult` indicates whether Firefox should show a notification when a DLP request is denied. The default is true.

3003 Control the installation, uninstallation and locking of extensions.
3005 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.
3007 This method will be deprecated in the near future.
3009 `Install` is a list of URLs or native paths for extensions to be installed.
3011 `Uninstall` is a list of extension IDs that should be uninstalled if found.
3013 `Locked` is a list of extension IDs that the user cannot disable or uninstall.

3087 ### ExtensionSettings
3088 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.
3090 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.
3092 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).
3093 Or you can ask the Mozilla Addons API, see [docs](https://mozilla.github.io/addons-server/topics/api/addons.html#detail), which returns the ID as `guid`: https://addons.mozilla.org/api/v5/addons/addon/ublock-origin/
3095 The configuration for each extension is another dictionary that can contain the fields documented below.
3097 | Name | Description |
3099 | `installation_mode` | Maps to a string indicating the installation mode for the extension. The valid strings are `allowed`,`blocked`,`force_installed`, and `normal_installed`.
3100 | `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.
3101 | `blocked`| Blocks installation of the extension and removes it from the device if already installed.
3102 | `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.
3103 | `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.
3104 | `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 ID with the extension ID or with the short name from the URL on AMO), https://addons.mozilla.org/firefox/downloads/latest/ID/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.
3105 | `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.
3106 | `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.
3107 | `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.
3108 | `restricted_domains` | An array of domains on which content scripts can't be run. This setting can be used only for the default configuration.
3109 | `updates_disabled` | (Firefox 89, Firefox ESR 78.11) Boolean that indicates whether or not to disable automatic updates for an individual extension.
3110 | `default_area` | (Firefox 113) String that indicates where to place the extension icon by default. Possible values are `navbar` and `menupanel`.
3111 | `temporarily_allow_weak_signatures`| (Firefox 127) A boolean that indicates whether to allow installing extensions signed using deprecated signature algorithms.
3113 **Compatibility:** Firefox 69, Firefox ESR 68.1 (As of Firefox 85, Firefox ESR 78.7, installing a theme makes it the default.)\

3442 ### GoToIntranetSiteForSingleWordEntryInAddressBar
3443 Whether to always go through the DNS server before sending a single word search string to a search engine.
3445 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.
3447 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.
3449 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.
3451 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`.
3453 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`.

3488 Configure default application handlers. This policy is based on the internal format of `handlers.json`.
3490 You can configure handlers based on a mime type (`mimeTypes`), a file's extension (`extensions`), or a protocol (`schemes`).
3492 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.
3494 | Name | Description |
3496 | `action`| Can be either `saveToDisk`, `useHelperApp`, `useSystemDefault`.
3497 | `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.
3498 | `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.
3499 | `name` | The display name of the handler (might not be used).
3500 | `path`| The native path to the executable to be used.
3501 | `uriTemplate`| A url to a web based application handler. The URL must be https and contain a %s to be used for substitution.

4276 1. The user will never be prompted to install updates
4277 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.
4278 3. The update UI will work as expected, unlike when using DisableAppUpdate.

5221 Set and lock preferences.
5223 **NOTE** On Windows, in order to use this policy, you must clear all settings in the old **Preferences (Deprecated)** section in group policy.
5225 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.

5304 Using the preference as the key, set the `Value` to the corresponding preference value.
5306 `Status` can be "default", "locked", "user" or "clear"
5308 * `"default"`: Read/Write: Settings appear as default even if factory default differs.
5309 * `"locked"`: Read-Only: Settings appear as default even if factory default differs.
5310 * `"user"`: Read/Write: Settings appear as changed if it differs from factory default.
5311 * `"clear"`: Read/Write: `Value` has no effect. Resets to factory defaults on each startup.
5313 `"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```.
5315 `"user"` preferences persist even if the policy is removed, so if you need to remove them, you should use the clear policy.
5317 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.
5319 See the examples below for more detail.
5321 IMPORTANT: Make sure you're only setting a particular preference using this mechanism and not some other way.

6829 Block websites from being visited. The parameters take an array of Match Patterns, as documented in https://developer.mozilla.org/en-US/Add-ons/WebExtensions/Match_patterns.
6830 The arrays are limited to 1000 entries each.
6832 If you want to block all URLs, you can use `<all_urls>` or `*://*/*`. You can't have just a `*` on the right side.
6834 For specific protocols, use `https://*/*` or `http://*/*`.
6836 As of Firefox 83 and Firefox ESR 78.5, file URLs are supported.
