[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.

568
569 See https://support.mozilla.org/kb/setting-certificate-authorities-firefox for more detail.
570
571 **Compatibility:** Firefox 60, Firefox ESR 60 (macOS support in Firefox 63, Firefox ESR 68)\

608 ### Certificates | Install
609
610 Install certificates into the Firefox certificate store. If only a filename is specified, Firefox searches for the file in the following locations:
611
612 - Windows
613 - %USERPROFILE%\AppData\Local\Mozilla\Certificates
614 - %USERPROFILE%\AppData\Roaming\Mozilla\Certificates
615 - macOS
616 - /Library/Application Support/Mozilla/Certificates
617 - ~/Library/Application Support/Mozilla/Certificates
618 - Linux
619 - /usr/lib/mozilla/certificates
620 - /usr/lib64/mozilla/certificates
621 - ~/.mozilla/certificates
622
623 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.
624
625 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.
626
627 Certificates are installed using the trust string `CT,CT,`.
628
629 Binary (DER) and ASCII (PEM) certificates are both supported.

673 ### Cookies
674 Configure cookie preferences.
675
676 `Allow` is a list of origins (not domains) where cookies are always allowed. You must include http or https.
677
678 `Block` is a list of origins (not domains) where cookies are always blocked. You must include http or https.
679
680 `Default` determines whether cookies are accepted at all.
681
682 `AcceptThirdParty` determines how third-party cookies are handled.
683
684 `ExpireAtSessionEnd` determines when cookies expire.
685
686 `RejectTracker` only rejects cookies for trackers.
687
688 `Locked` prevents the user from changing cookie preferences.

2144 ### ExtensionSettings
2145 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.
2146
2147 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.
2148
2149 To obtain an extension ID, install the extension and go to about:support. You will see the ID in the Extensions section.
2150
2151 The configuration for each extension is another dictionary that can contain the fields documented below.
2152
2153 | Name | Description |
2154 | --- | --- |
2155 | `installation_mode` | Maps to a string indicating the installation mode for the extension. The valid strings are `allowed`,`blocked`,`force_installed`, and `normal_installed`.
2156 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`allowed` | Allows the extension to be installed by the user. This is the default behavior.
2157 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`blocked`| Blocks installation of the extension and removes it from the device if already installed.
2158 | &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.
2159 | &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.
2160 | `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.
2161 | `install_sources` | 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.
2162 | `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.
2163 | `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.

3016 ### Permissions

3020
3021 `Block` is a list of origins where the feature is not allowed.

3023 `BlockNewRequests` determines whether or not new requests can be made for the feature.
3024
3025 `Locked` prevents the user from changing preferences for the feature.
3026
3027 `Default` specifies the default value for Autoplay. block-audio-video is not supported on Firefox ESR 68.
3028
