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.

890 Note: [`ManagedBookmarks`](#managedbookmarks) is the new recommended way to add bookmarks. This policy will continue to be supported.
892 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.
894 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.

1012 Trust certificates that have been added to the operating system certificate store by a user or administrator.
1014 Note: This policy only works on Windows and macOS. For Linux discussion, see [bug 1600509](https://bugzilla.mozilla.org/show_bug.cgi?id=1600509).
1016 See https://support.mozilla.org/kb/setting-certificate-authorities-firefox for more detail.

1055 ### Certificates | Install
1057 Install certificates into the Firefox certificate store. If only a filename is specified, Firefox searches for the file in the following locations:
1060 - %USERPROFILE%\AppData\Local\Mozilla\Certificates
1061 - %USERPROFILE%\AppData\Roaming\Mozilla\Certificates
1063 - /Library/Application Support/Mozilla/Certificates
1064 - ~/Library/Application Support/Mozilla/Certificates
1066 - /usr/lib/mozilla/certificates
1067 - /usr/lib64/mozilla/certificates
1068 - ~/.mozilla/certificates
1070 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.
1072 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.
1074 Certificates are installed using the trust string `CT,CT,`.
1076 Binary (DER) and ASCII (PEM) certificates are both supported.

2785 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.
2787 This method will be deprecated in the near future.
2789 `Install` is a list of URLs or native paths for extensions to be installed.
2791 `Uninstall` is a list of extension IDs that should be uninstalled if found.

2867 ### ExtensionSettings
2868 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.
2870 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.
2872 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).
2874 The configuration for each extension is another dictionary that can contain the fields documented below.
2876 | Name | Description |
2878 | `installation_mode` | Maps to a string indicating the installation mode for the extension. The valid strings are `allowed`,`blocked`,`force_installed`, and `normal_installed`.
2879 | `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.
2880 | `blocked`| Blocks installation of the extension and removes it from the device if already installed.
2881 | `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.
2882 | `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.
2883 | `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.
2884 | `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.
2885 | `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.
2886 | `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.

3189 ### GoToIntranetSiteForSingleWordEntryInAddressBar
3190 Whether to always go through the DNS server before sending a single word search string to a search engine.
3192 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.
3194 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.
3196 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.
3198 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`.
3200 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`.

3235 Configure default application handlers. This policy is based on the internal format of `handlers.json`.
3237 You can configure handlers based on a mime type (`mimeTypes`), a file's extension (`extensions`), or a protocol (`schemes`).
3239 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.
3241 | Name | Description |
3243 | `action`| Can be either `saveToDisk`, `useHelperApp`, `useSystemDefault`.
3244 | `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.
3245 | `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.
3246 | `name` | The display name of the handler (might not be used).
3247 | `path`| The native path to the executable to be used.
3248 | `uriTemplate`| A url to a web based application handler. The URL must be https and contain a %s to be used for substitution.

3994 ### ManualAppUpdateOnly
3996 Switch to manual updates only.
3998 If this policy is enabled:
3999 1. The user will never be prompted to install updates
4000 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.
4001 3. The update UI will work as expected, unlike when using DisableAppUpdate.
4003 This policy is primarily intended for advanced end users, not for enterprises, but it is available via GPO.

4420 `Block` is a list of origins where the feature is not allowed.
4422 `BlockNewRequests` determines whether or not new requests can be made for the feature.

4936 Using the preference as the key, set the `Value` to the corresponding preference value.
4938 `Status` can be "default", "locked", "user" or "clear"
4940 * `"default"`: Read/Write: Settings appear as default even if factory default differs.
4941 * `"locked"`: Read-Only: Settings appear as default even if factory default differs.
4942 * `"user"`: Read/Write: Settings appear as changed if it differs from factory default.
4943 * `"clear"`: Read/Write: `Value` has no effect. Resets to factory defaults on each startup.
4945 `"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```.
4947 `"user"` preferences persist even if the policy is removed, so if you need to remove them, you should use the clear policy.
4949 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.
4951 See the examples below for more detail.
4953 IMPORTANT: Make sure you're only setting a particular preference using this mechanism and not some other way.
