1 **These policies are in active development and so might contain changes that do not work with current versions of Firefox.**
2
3 **You should use the [officially released versions](https://github.com/mozilla/policy-templates/releases) if you are deploying changes.**
4
5 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`.

612 ### Certificates | Install
613
614 Install certificates into the Firefox certificate store. If only a filename is specified, Firefox searches for the file in the following locations:
615
616 - Windows
617 - %USERPROFILE%\AppData\Local\Mozilla\Certificates
618 - %USERPROFILE%\AppData\Roaming\Mozilla\Certificates
619 - macOS
620 - /Library/Application Support/Mozilla/Certificates
621 - ~/Library/Application Support/Mozilla/Certificates
622 - Linux
623 - /usr/lib/mozilla/certificates
624 - /usr/lib64/mozilla/certificates
625 - ~/.mozilla/certificates
626
627 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.
628
629 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.
630
631 Certificates are installed using the trust string `CT,CT,`.
632
633 Binary (DER) and ASCII (PEM) certificates are both supported.

677 ### Cookies
678 Configure cookie preferences.
679
680 `Allow` is a list of origins (not domains) where cookies are always allowed. You must include http or https.
681
682 `Block` is a list of origins (not domains) where cookies are always blocked. You must include http or https.
683
684 `Default` determines whether cookies are accepted at all.
685
686 `AcceptThirdParty` determines how third-party cookies are handled.
687
688 `ExpireAtSessionEnd` determines when cookies expire.
689
690 `RejectTracker` only rejects cookies for trackers.
691
692 `Locked` prevents the user from changing cookie preferences.

2164 ### ExtensionSettings
2165 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.
2166
2167 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.
2168
2169 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).
2170
2171 The configuration for each extension is another dictionary that can contain the fields documented below.
2172
2173 | Name | Description |
2174 | --- | --- |
2175 | `installation_mode` | Maps to a string indicating the installation mode for the extension. The valid strings are `allowed`,`blocked`,`force_installed`, and `normal_installed`.
2176 | &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.
2177 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`blocked`| Blocks installation of the extension and removes it from the device if already installed.
2178 | &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.
2179 | &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.
2180 | `install_url`| Maps to a URL indicating where Firefox can download a force_installed or normal_installed extension. 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. If installing from the local file system, use a file:/// URL. 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.
2181 | `install_sources` | A list of sources from which installing extensions is allowed. **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. If you want to allow the install of extensions from the recommended add-ons page, you must add `about:addons` to this list.
2182 | `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", "langpack" This setting can be used only for the default configuration.
2183 | `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.
2184 | `restricted_domains` | An array of domains on which content scripts can't be run. This setting can be used only for the default configuration.

2409 ### Handlers
2410 Configure default application handlers. This policy is based on the internal format of `handlers.json`.
2411
2412 You can configure handlers based on a mime type (`mimeTypes`), a file's extension (`extensions`), or a protocol (`schemes`).
2413
2414 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.
2415
2416 | Name | Description |
2417 | --- | --- |
2418 | `action`| Can be either `saveToDisk`, `useHelperApp`, `useSystemDefault`.
2419 | `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.
2420 | `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.
2421 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`name` | The display name of the handler (might not be used).
2422 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`path`| The native path to the executable to be used.
2423 | &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.

3237 ### Permissions
3238 Set permissions associated with camera, microphone, location, notifications, and autoplay. Because these are origins, not domains, entries with unique ports must be specified separately. See examples below.
3239
3240 `Allow` is a list of origins where the feature is allowed.
3241
3242 `Block` is a list of origins where the feature is not allowed.
3243
3244 `BlockNewRequests` determines whether or not new requests can be made for the feature.
3245
3246 `Locked` prevents the user from changing preferences for the feature.
3247
3248 `Default` specifies the default value for Autoplay. block-audio-video is not supported on Firefox ESR 68.
3249
3250 **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)\
