Fix typos in policies.json code snippet areas
[policy-templates.git] / 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`.

521 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.

667 ### Certificates | Install
668
669 Install certificates into the Firefox certificate store. If only a filename is specified, Firefox searches for the file in the following locations:
670
671 - Windows
672 - %USERPROFILE%\AppData\Local\Mozilla\Certificates
673 - %USERPROFILE%\AppData\Roaming\Mozilla\Certificates
674 - macOS
675 - /Library/Application Support/Mozilla/Certificates
676 - ~/Library/Application Support/Mozilla/Certificates
677 - Linux
678 - /usr/lib/mozilla/certificates
679 - /usr/lib64/mozilla/certificates
680 - ~/.mozilla/certificates
681
682 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.
683
684 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.
685
686 Certificates are installed using the trust string `CT,CT,`.
687
688 Binary (DER) and ASCII (PEM) certificates are both supported.

732 ### Cookies
733 Configure cookie preferences.
734
735 `Allow` is a list of origins (not domains) where cookies are always allowed. You must include http or https.
736
737 `AllowSession` is a list of origins (not domains) where cookies are only allowed for the current session. You must include http or https.
738
739 `Block` is a list of origins (not domains) where cookies are always blocked. You must include http or https.
740
741 `Default` determines whether cookies are accepted at all.
742
743 `AcceptThirdParty` determines how third-party cookies are handled.
744
745 `ExpireAtSessionEnd` determines when cookies expire.
746
747 `RejectTracker` only rejects cookies for trackers.
748
749 `Locked` prevents the user from changing cookie preferences.

2224 Control the installation, uninstallation and locking of extensions.
2225
2226 While this policy is not technically deprecated, it is recommended 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.
2227
2228 `Install` is a list of URLs or native paths for extensions to be installed.
2229
2230 `Uninstall` is a list of extension IDs that should be uninstalled if found.
2231
2232 `Locked` is a list of extension IDs that the user cannot disable or uninstall.

2309 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.
2310
2311 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).
2312
2313 The configuration for each extension is another dictionary that can contain the fields documented below.
2314
2315 | Name | Description |
2316 | --- | --- |
2317 | `installation_mode` | Maps to a string indicating the installation mode for the extension. The valid strings are `allowed`,`blocked`,`force_installed`, and `normal_installed`.
2318 | &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.
2319 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`blocked`| Blocks installation of the extension and removes it from the device if already installed.
2320 | &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.
2321 | &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.
2322 | `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.
2323 | `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.
2324 | `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.
2325 | `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.
2326 | `restricted_domains` | An array of domains on which content scripts can't be run. This setting can be used only for the default configuration.

2553 ### Handlers
2554 Configure default application handlers. This policy is based on the internal format of `handlers.json`.
2555
2556 You can configure handlers based on a mime type (`mimeTypes`), a file's extension (`extensions`), or a protocol (`schemes`).
2557
2558 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.
2559
2560 | Name | Description |
2561 | --- | --- |
2562 | `action`| Can be either `saveToDisk`, `useHelperApp`, `useSystemDefault`.
2563 | `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.
2564 | `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.
2565 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`name` | The display name of the handler (might not be used).
2566 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`path`| The native path to the executable to be used.
2567 | &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.

3214 ### ManualAppUpdateOnly
3215
3216 Switch to manual updates only.
3217
3218 If this policy is enabled:
3219 1. The user will never be prompted to install updates
3220 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.
3221 3. The update UI will work as expected, unlike when using DisableAppUpdate.
3222
3223 This policy is primarily intended for advanced end users, not for enterprises.

3237 ### PrimaryPassword

3241
3242 If both DisableMasterPasswordCreation and PrimaryPassword are used, DisableMasterPasswordCreation takes precedent.

3560 ### PDFjs
3561 Disable or configure PDF.js, the built-in PDF viewer.
3562
3563 If `Enabled` is set to false, the built-in PDF viewer is disabled.
3564
3565 If `EnablePermissions` is set to true, the built-in PDF viewer will honor document permissions like preventing the copying of text.
3566
3567 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.

3611 ### Permissions
3612 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.
3613
3614 `Allow` is a list of origins where the feature is allowed.
3615
3616 `Block` is a list of origins where the feature is not allowed.
3617
3618 `BlockNewRequests` determines whether or not new requests can be made for the feature.
3619
3620 `Locked` prevents the user from changing preferences for the feature.
3621
3622 `Default` specifies the default value for Autoplay. block-audio-video is not supported on Firefox ESR 68.
3623
3624 **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)\
3625 **CCK2 Equivalent:** N/A\

4047 | &nbsp;&nbsp;&nbsp;&nbsp;If set to Select Automatically, Firefox automatically chooses the default personal certificate.
4048 | security.insecure_connection_text.enabled | bool | false
4049 | &nbsp;&nbsp;&nbsp;&nbsp;If set to true, adds the words "Not Secure" for insecure sites.
4050 | security.insecure_connection_text.pbmode.enabled | bool | false
4051 | &nbsp;&nbsp;&nbsp;&nbsp;If set to true, adds the words "Not Secure" for insecure sites in private browsing.

4053 | &nbsp;&nbsp;&nbsp;&nbsp;If set to false, remove the warning for inscure login fields.
4054 | security.mixed_content.block_active_content | boolean | true
4055 | &nbsp;&nbsp;&nbsp;&nbsp;If false, mixed active content (HTTP and HTTPS) is not blocked.

4057 | &nbsp;&nbsp;&nbsp;&nbsp;If true, client certificates are loaded from the operating system certificate store.
4058 | security.ssl.errorReporting.enabled | boolean | true
4059 | &nbsp;&nbsp;&nbsp;&nbsp;If false, SSL errors cannot be sent to Mozilla.
4060 | security.tls.hello_downgrade_check | boolean | true
4061 | &nbsp;&nbsp;&nbsp;&nbsp;If false, the TLS 1.3 downgrade check is disabled.
4062 | security.tls.version.enable-deprecated | boolean | false

4064 | security.warn_submit_secure_to_insecure | boolean | true
4065 | &nbsp;&nbsp;&nbsp;&nbsp;If false, no warning is shown when submitting s form from https to http.
4066 &nbsp;
4067
4068 Using the preference as the key, set the `Value` to the corresponding preference value.
4069
4070 `Status` can be "default", "locked", "user" or "clear"
4071
4072 Default preferences can be modified by the user.
4073
4074 If a value is locked, it is also set as the default.
4075
4076 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.
4077
4078 User preferences persist even if the policy is removed, so if you need to remove them, you should use the clear policy.
4079
4080 See the examples below for more detail.
4081
4082 IMPORTANT: Make sure you're only setting a particular preference using this mechanism and not some other way.
