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

891 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.
893 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.
895 Certificates are installed using the trust string `CT,CT,`.
897 Binary (DER) and ASCII (PEM) certificates are both supported.

2443 Control the installation, uninstallation and locking of extensions.
2445 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.
2447 `Install` is a list of URLs or native paths for extensions to be installed.
2449 `Uninstall` is a list of extension IDs that should be uninstalled if found.
2451 `Locked` is a list of extension IDs that the user cannot disable or uninstall.

2525 ### ExtensionSettings
2526 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.
2528 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.
2530 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).
2532 The configuration for each extension is another dictionary that can contain the fields documented below.
2534 | Name | Description |
2536 | `installation_mode` | Maps to a string indicating the installation mode for the extension. The valid strings are `allowed`,`blocked`,`force_installed`, and `normal_installed`.
2537 | `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.
2538 | `blocked`| Blocks installation of the extension and removes it from the device if already installed.
2539 | `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.
2540 | `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.
2541 | `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.
2542 | `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.
2543 | `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.
2544 | `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.
2545 | `restricted_domains` | An array of domains on which content scripts can't be run. This setting can be used only for the default configuration.
2546 | `updates_disabled` | (Firefox 89, Firefox ESR 78.11) Boolean that indicates whether or not to disable automatic updates for an individual extension.
2548 **Compatibility:** Firefox 69, Firefox ESR 68.1 (As of Firefox 85, Firefox ESR 78.7, installing a theme makes it the default.)\

3522 Switch to manual updates only.
3524 If this policy is enabled:
3525 1. The user will never be prompted to install updates
3526 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.
3527 3. The update UI will work as expected, unlike when using DisableAppUpdate.

4325 Set and lock preferences.
4327 **NOTE** On Windows, in order to use this policy, you must clear all settings in the old **Preferences (Deprecated)** section.
4329 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.
4331 Preferences that start with the following prefixes are supported:
4334 app.update.* (Firefox 86, Firefox 78.8)
4336 datareporting.policy.
4339 general.autoScroll (Firefox 83, Firefox ESR 78.5)
4340 general.smoothScroll (Firefox 83, Firefox ESR 78.5)
4344 keyword.enabled (Firefox 95, Firefox ESR 91.4)
4349 pdfjs. (Firefox 84, Firefox ESR 78.6)
4352 signon. (Firefox 83, Firefox ESR 78.5)
4353 spellchecker. (Firefox 84, Firefox ESR 78.6)
4354 toolkit.legacyUserProfileCustomizations.stylesheets (Firefox 95, Firefox ESR 91.4)
4358 as well as the following security preferences:
4359 | Preference | Type | Default
4361 | security.default_personal_cert | string | Ask Every Time
4362 | If set to Select Automatically, Firefox automatically chooses the default personal certificate.
4363 | security.insecure_connection_text.enabled | bool | false
4364 | If set to true, adds the words "Not Secure" for insecure sites.
4365 | security.insecure_connection_text.pbmode.enabled | bool | false
4366 | If set to true, adds the words "Not Secure" for insecure sites in private browsing.
4367 | security.insecure_field_warning.contextual.enabled | bool | true
4368 | If set to false, remove the warning for inscure login fields.
4369 | security.mixed_content.block_active_content | boolean | true
4370 | If false, mixed active content (HTTP and HTTPS) is not blocked.
4371 | security.osclientcerts.autoload | boolean | false
4372 | If true, client certificates are loaded from the operating system certificate store.
4373 | security.ssl.errorReporting.enabled | boolean | true
4374 | If false, SSL errors cannot be sent to Mozilla.
4375 | security.tls.enable_0rtt_data | boolean | true
4376 | If false, TLS early data is turned off (Firefox 93, Firefox 91.2, Firefox 78.15).
4377 | security.tls.hello_downgrade_check | boolean | true
4378 | If false, the TLS 1.3 downgrade check is disabled.
4379 | security.tls.version.enable-deprecated | boolean | false
4380 | If true, browser will accept TLS 1.0. and TLS 1.1 (Firefox 86, Firefox 78.8).
4381 | security.warn_submit_secure_to_insecure | boolean | true
4382 | If false, no warning is shown when submitting a form from https to http.
4385 Using the preference as the key, set the `Value` to the corresponding preference value.
4387 `Status` can be "default", "locked", "user" or "clear"
4389 * `"default"`: Read/Write: Settings appear as default even if factory default differs.
4390 * `"locked"`: Read-Only: Settings appear as default even if factory default differs.
4391 * `"user"`: Read/Write: Settings appear as changed if it differs from factory default.
4392 * `"clear"`: Read/Write: `Value` has no effect. Resets to factory defaults on each startup.
4394 `"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. An example of this is ```toolkit.legacyUserProfileCustomizations.stylesheets```.
4396 `"user"` preferences persist even if the policy is removed, so if you need to remove them, you should use the clear policy.
4398 See the examples below for more detail.
4400 IMPORTANT: Make sure you're only setting a particular preference using this mechanism and not some other way.
