   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`.

 575 ### Certificates
 576
 577 ### Certificates | ImportEnterpriseRoots
 578
 579 Trust certificates that have been added to the operating system certificate store by a user or administrator.
 580
 581 Note: This policy only works on Windows and macOS. For Linux discussion, see [bug 1600509](https://bugzilla.mozilla.org/show_bug.cgi?id=1600509).
 582
 583 See https://support.mozilla.org/kb/setting-certificate-authorities-firefox for more detail.

 620 }
 621 ```
 622 ### Certificates | Install
 623
 624 Install certificates into the Firefox certificate store. If only a filename is specified, Firefox searches for the file in the following locations:
 625
 626 - Windows
 627   - %USERPROFILE%\AppData\Local\Mozilla\Certificates
 628   - %USERPROFILE%\AppData\Roaming\Mozilla\Certificates
 629 - macOS
 630   - /Library/Application Support/Mozilla/Certificates
 631   - ~/Library/Application Support/Mozilla/Certificates
 632 - Linux
 633   - /usr/lib/mozilla/certificates
 634   - /usr/lib64/mozilla/certificates
 635   - ~/.mozilla/certificates
 636
 637 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.
 638
 639 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.
 640
 641 Certificates are installed using the trust string `CT,CT,`.
 642
 643 Binary (DER) and ASCII (PEM) certificates are both supported.
 644
 645 **Compatibility:** Firefox 64, Firefox ESR 64\
 646 **CCK2 Equivalent:** `certs.ca`\

 687 ### Cookies
 688 Configure cookie preferences.
 689
 690 `Allow` is a list of origins (not domains) where cookies are always allowed. You must include http or https.
 691
 692 `AllowSession` is a list of origins (not domains) where cookies are only allowed for the current session. You must include http or https.
 693
 694 `Block` is a list of origins (not domains) where cookies are always blocked. You must include http or https.
 695
 696 `Default` determines whether cookies are accepted at all.
 697
 698 `AcceptThirdParty` determines how third-party cookies are handled.
 699
 700 `ExpireAtSessionEnd` determines when cookies expire.
 701
 702 `RejectTracker` only rejects cookies for trackers.
 703
 704 `Locked` prevents the user from changing cookie preferences.
 705

2255 ### ExtensionSettings
2256 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.
2257
2258 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.
2259
2260 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).
2261
2262 The configuration for each extension is another dictionary that can contain the fields documented below.
2263
2264 | Name | Description |
2265 | --- | --- |
2266 | `installation_mode` | Maps to a string indicating the installation mode for the extension. The valid strings are `allowed`,`blocked`,`force_installed`, and `normal_installed`.
2267 | &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.
2268 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`blocked`| Blocks installation of the extension and removes it from the device if already installed.
2269 | &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.
2270 | &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.
2271 | `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. 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.
2272 | `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.
2273 | `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.
2274 | `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.
2275 | `restricted_domains` | An array of domains on which content scripts can't be run. This setting can be used only for the default configuration.
2276

2502 ### Handlers
2503 Configure default application handlers. This policy is based on the internal format of `handlers.json`.
2504
2505 You can configure handlers based on a mime type (`mimeTypes`), a file's extension (`extensions`), or a protocol (`schemes`).
2506
2507 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.
2508
2509 | Name | Description |
2510 | --- | --- |
2511 | `action`| Can be either `saveToDisk`, `useHelperApp`, `useSystemDefault`.
2512 | `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.
2513 | `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.
2514 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`name` | The display name of the handler (might not be used).
2515 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`path`| The native path to the executable to be used.
2516 | &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.

3534 ### Permissions
3535 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.
3536
3537 `Allow` is a list of origins where the feature is allowed.
3538
3539 `Block` is a list of origins where the feature is not allowed.
3540
3541 `BlockNewRequests` determines whether or not new requests can be made for the feature.
3542
3543 `Locked` prevents the user from changing preferences for the feature.
3544
3545 `Default` specifies the default value for Autoplay. block-audio-video is not supported on Firefox ESR 68.
3546
3547 **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)\

3936 ### Preferences
3937 Set and lock preferences.
3938
3939 **NOTE** On Windows, in order to use this policy, you must clear all settings in the old **Preferences (Deprecated)** section.
3940
3941 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.
3942
3943 Preferences that start with the following prefixes are supported:
3944 ```
3945 accessibility.
3946 browser.
3947 datareporting.policy.
3948 dom.
3949 extensions.
3950 general.autoScroll (Firefox 83, Firefox ESR 78.5)
3951 general.smoothScroll (Firefox 83, Firefox ESR 78.5)
3952 geo.
3953 intl.
3954 layout.
3955 media.
3956 network.
3957 pdfjs. (Firefox 84, Firefox ESR 78.6)
3958 places.
3959 print.
3960 signon. (Firefox 83, Firefox ESR 78.5)
3961 spellchecker. (Firefox 84, Firefox ESR 78.6)
3962 ui.
3963 widget.
3964 ```
3965 as well as the following security preferences:
3966 | Preference | Type | Default
3967 | --- | --- | ---
3968 | security.default_personal_cert | string | Ask Every Time
3969 | &nbsp;&nbsp;&nbsp;&nbsp;If set to Select Automatically, Firefox automatically chooses the default personal certificate.
3970 | security.insecure_connection_text.enabled | bool | false
3971 | &nbsp;&nbsp;&nbsp;&nbsp;If set to true, adds the words "Not Secure" for insecure sites.
3972 | security.insecure_connection_text.pbmode.enabled | bool | false
3973 | &nbsp;&nbsp;&nbsp;&nbsp;If set to true, adds the words "Not Secure" for insecure sites in private browsing.
3974 | security.insecure_field_warning.contextual.enabled | bool | true
3975 | &nbsp;&nbsp;&nbsp;&nbsp;If set to false, remove the warning for inscure login fields.
3976 | security.mixed_content.block_active_content | boolean | true
3977 | &nbsp;&nbsp;&nbsp;&nbsp;If false, mixed active content (HTTP and HTTPS) is not blocked.
3978 | security.osclientcerts.autoload | boolean | false
3979 | &nbsp;&nbsp;&nbsp;&nbsp;If true, client certificates are loaded from the operating system certificate store.
3980 | security.ssl.errorReporting.enabled | boolean | true
3981 | &nbsp;&nbsp;&nbsp;&nbsp;If false, SSL errors cannot be sent to Mozilla.
3982 | security.tls.hello_downgrade_check | boolean | true
3983 | &nbsp;&nbsp;&nbsp;&nbsp;If false, the TLS 1.3 downgrade check is disabled.
3984 | security.warn_submit_secure_to_insecure | boolean | true
3985 | &nbsp;&nbsp;&nbsp;&nbsp;If false, no warning is shown when submitting s form from https to http.
3986 &nbsp;
3987
3988 Using the preference as the key, set the `Value` to the corresponding preference value.
3989
3990 `Status` can be "default", "locked", "user" or "clear"
3991
3992 Default preferences can be modified by the user.
3993
3994 If a value is locked, it is also set as the default.
3995
3996 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.
3997
3998 User preferences persist even if the policy is removed, so if you need to remove them, you should use the clear policy.
3999
4000 See the examples below for more detail.
4001
4002 IMPORTANT: Make sure you're only setting a particular preference using this mechanism and not some other way.
