README.md

   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`.

 567 ### Certificates
 568
 569 ### Certificates | ImportEnterpriseRoots
 570
 571 Trust certificates that have been added to the operating system certificate store by a user or administrator.
 572
 573 Note: This policy only works on Windows and macOS. For Linux discussion, see [bug 1600509](https://bugzilla.mozilla.org/show_bug.cgi?id=1600509).
 574
 575 See https://support.mozilla.org/kb/setting-certificate-authorities-firefox for more detail.

 613 ```
 614 ### Certificates | Install
 615
 616 Install certificates into the Firefox certificate store. If only a filename is specified, Firefox searches for the file in the following locations:
 617
 618 - Windows
 619   - %USERPROFILE%\AppData\Local\Mozilla\Certificates
 620   - %USERPROFILE%\AppData\Roaming\Mozilla\Certificates
 621 - macOS
 622   - /Library/Application Support/Mozilla/Certificates
 623   - ~/Library/Application Support/Mozilla/Certificates
 624 - Linux
 625   - /usr/lib/mozilla/certificates
 626   - /usr/lib64/mozilla/certificates
 627   - ~/.mozilla/certificates
 628
 629 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.
 630
 631 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.
 632
 633 Certificates are installed using the trust string `CT,CT,`.
 634
 635 Binary (DER) and ASCII (PEM) certificates are both supported.
 636
 637 **Compatibility:** Firefox 64, Firefox ESR 64\
 638 **CCK2 Equivalent:** `certs.ca`\

 679 ### Cookies
 680 Configure cookie preferences.
 681
 682 `Allow` is a list of origins (not domains) where cookies are always allowed. You must include http or https.
 683
 684 `AllowSession` is a list of origins (not domains) where cookies are only allowed for the current session. You must include http or https.
 685
 686 `Block` is a list of origins (not domains) where cookies are always blocked. You must include http or https.
 687
 688 `Default` determines whether cookies are accepted at all.
 689
 690 `AcceptThirdParty` determines how third-party cookies are handled.
 691
 692 `ExpireAtSessionEnd` determines when cookies expire.
 693
 694 `RejectTracker` only rejects cookies for trackers.
 695
 696 `Locked` prevents the user from changing cookie preferences.
 697

2245 ### ExtensionSettings
2246 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.
2247
2248 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.
2249
2250 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).
2251
2252 The configuration for each extension is another dictionary that can contain the fields documented below.
2253
2254 | Name | Description |
2255 | --- | --- |
2256 | `installation_mode` | Maps to a string indicating the installation mode for the extension. The valid strings are `allowed`,`blocked`,`force_installed`, and `normal_installed`.
2257 | &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.
2258 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`blocked`| Blocks installation of the extension and removes it from the device if already installed.
2259 | &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.
2260 | &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.
2261 | `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.
2262 | `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.
2263 | `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.
2264 | `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.
2265 | `restricted_domains` | An array of domains on which content scripts can't be run. This setting can be used only for the default configuration.

2492 ### Handlers
2493 Configure default application handlers. This policy is based on the internal format of `handlers.json`.
2494
2495 You can configure handlers based on a mime type (`mimeTypes`), a file's extension (`extensions`), or a protocol (`schemes`).
2496
2497 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.
2498
2499 | Name | Description |
2500 | --- | --- |
2501 | `action`| Can be either `saveToDisk`, `useHelperApp`, `useSystemDefault`.
2502 | `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.
2503 | `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.
2504 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`name` | The display name of the handler (might not be used).
2505 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`path`| The native path to the executable to be used.
2506 | &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.

3315 ### PDFjs
3316 Disable or configure PDF.js, the built-in PDF viewer.

3320 If `EnablePermissions` is set to true, the built-in PDF viewer will honor document permissions like preventing the copying of text.
3321
3322 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.

3365 ### Permissions
3366 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.
3367
3368 `Allow` is a list of origins where the feature is allowed.
3369
3370 `Block` is a list of origins where the feature is not allowed.
3371
3372 `BlockNewRequests` determines whether or not new requests can be made for the feature.
3373
3374 `Locked` prevents the user from changing preferences for the feature.
3375
3376 `Default` specifies the default value for Autoplay. block-audio-video is not supported on Firefox ESR 68.
3377
3378 **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)\

3756 ### Preferences
3757 Set and lock preferences.
3758
3759 **NOTE** On Windows, in order to use this policy, you must clear all settings in the old **Preferences (Deprecated)** section.
3760
3761 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.
3762
3763 Preferences that start with the following prefixes are supported:
3764 ```
3765 accessibility.
3766 browser.
3767 datareporting.policy.
3768 dom.
3769 extensions.
3770 general.autoScroll (Firefox 83, Firefox ESR 78.5)
3771 general.smoothScroll (Firefox 83, Firefox ESR 78.5)
3772 geo.
3773 intl.
3774 layout.
3775 media.
3776 network.
3777 places.
3778 print.
3779 signon. (Firefox 83, Firefox ESR 78.5)
3780 ui.
3781 widget.
3782 ```
3783 as well as the following security preferences:
3784 | Preference | Type | Default
3785 | --- | --- | ---
3786 | security.default_personal_cert | string | Ask Every Time
3787 | &nbsp;&nbsp;&nbsp;&nbsp;If set to Select Automatically, Firefox automatically chooses the default personal certificate.
3788 | security.insecure_connection_text.enabled | bool | false
3789 | &nbsp;&nbsp;&nbsp;&nbsp;If set to true, adds the words "Not Secure" for insecure sites.
3790 | security.insecure_connection_text.pbmode.enabled | bool | false
3791 | &nbsp;&nbsp;&nbsp;&nbsp;If set to true, adds the words "Not Secure" for insecure sites in private browsing.
3792 | security.insecure_field_warning.contextual.enabled | bool | true
3793 | &nbsp;&nbsp;&nbsp;&nbsp;If set to false, remove the warning for inscure login fields.
3794 | security.mixed_content.block_active_content | boolean | true
3795 | &nbsp;&nbsp;&nbsp;&nbsp;If false, mixed active content (HTTP and HTTPS) is not blocked.
3796 | security.osclientcerts.autoload | boolean | false
3797 | &nbsp;&nbsp;&nbsp;&nbsp;If true, client certificates are loaded from the operating system certificate store.
3798 | security.ssl.errorReporting.enabled | boolean | true
3799 | &nbsp;&nbsp;&nbsp;&nbsp;If false, SSL errors cannot be sent to Mozilla.
3800 | security.tls.hello_downgrade_check | boolean | true
3801 | &nbsp;&nbsp;&nbsp;&nbsp;If false, the TLS 1.3 downgrade check is disabled.
3802 | security.warn_submit_secure_to_insecure | boolean | true
3803 | &nbsp;&nbsp;&nbsp;&nbsp;If false, no warning is shown when submitting s form from https to http.
3804 &nbsp;
3805
3806 Using the preference as the key, set the `Value` to the corresponding preference value.
3807
3808 `Status` can be "default", "locked", "user" or "clear"
3809
3810 Default preferences can be modified by the user.
3811
3812 If a value is locked, it is also set as the default.
3813
3814 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.
3815
3816 User preferences persist even if the policy is removed, so if you need to remove them, you should use the clear policy.
3817
3818 See the examples below for more detail.
3819
3820 IMPORTANT: Make sure you're only setting a particular preference using this mechanism and not some other way.
