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`.

822 ### Certificates | Install
824 Install certificates into the Firefox certificate store. If only a filename is specified, Firefox searches for the file in the following locations:
827 - %USERPROFILE%\AppData\Local\Mozilla\Certificates
828 - %USERPROFILE%\AppData\Roaming\Mozilla\Certificates
830 - /Library/Application Support/Mozilla/Certificates
831 - ~/Library/Application Support/Mozilla/Certificates
833 - /usr/lib/mozilla/certificates
834 - /usr/lib64/mozilla/certificates
835 - ~/.mozilla/certificates
837 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.
839 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.
841 Certificates are installed using the trust string `CT,CT,`.
843 Binary (DER) and ASCII (PEM) certificates are both supported.

2390 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.
2392 `Install` is a list of URLs or native paths for extensions to be installed.
2394 `Uninstall` is a list of extension IDs that should be uninstalled if found.
2396 `Locked` is a list of extension IDs that the user cannot disable or uninstall.

2470 ### ExtensionSettings
2471 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.
2473 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.
2475 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).
2477 The configuration for each extension is another dictionary that can contain the fields documented below.
2479 | Name | Description |
2481 | `installation_mode` | Maps to a string indicating the installation mode for the extension. The valid strings are `allowed`,`blocked`,`force_installed`, and `normal_installed`.
2482 | `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.
2483 | `blocked`| Blocks installation of the extension and removes it from the device if already installed.
2484 | `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.
2485 | `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.
2486 | `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.
2487 | `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.
2488 | `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.
2489 | `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.
2490 | `restricted_domains` | An array of domains on which content scripts can't be run. This setting can be used only for the default configuration.
2491 | `updates_disabled` | (Firefox 89, Firefox ESR 78.11) Boolean that indicates whether or not to disable automatic updates for an individual extension.
2493 **Compatibility:** Firefox 69, Firefox ESR 68.1 (As of Firefox 85, Firefox ESR 78.7, installing a theme makes it the default.)\

3465 ### ManualAppUpdateOnly
3467 Switch to manual updates only.
3469 If this policy is enabled:
3470 1. The user will never be prompted to install updates
3471 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.
3472 3. The update UI will work as expected, unlike when using DisableAppUpdate.
3474 This policy is primarily intended for advanced end users, not for enterprises.

4226 Set and lock preferences.
4228 **NOTE** On Windows, in order to use this policy, you must clear all settings in the old **Preferences (Deprecated)** section.
4230 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.
4232 Preferences that start with the following prefixes are supported:
4235 app.update.* (Firefox 86, Firefox 78.8)
4237 datareporting.policy.
4240 general.autoScroll (Firefox 83, Firefox ESR 78.5)
4241 general.smoothScroll (Firefox 83, Firefox ESR 78.5)
4245 keyword.enabled (Firefox 95, Firefox ESR 91.4)
4250 pdfjs. (Firefox 84, Firefox ESR 78.6)
4253 signon. (Firefox 83, Firefox ESR 78.5)
4254 spellchecker. (Firefox 84, Firefox ESR 78.6)
4255 toolkit.legacyUserProfileCustomizations.stylesheets (Firefox 95, Firefox ESR 91.4)
4259 as well as the following security preferences:
4260 | Preference | Type | Default
4262 | security.default_personal_cert | string | Ask Every Time
4263 | If set to Select Automatically, Firefox automatically chooses the default personal certificate.
4264 | security.insecure_connection_text.enabled | bool | false
4265 | If set to true, adds the words "Not Secure" for insecure sites.
4266 | security.insecure_connection_text.pbmode.enabled | bool | false
4267 | If set to true, adds the words "Not Secure" for insecure sites in private browsing.
4268 | security.insecure_field_warning.contextual.enabled | bool | true
4269 | If set to false, remove the warning for inscure login fields.
4270 | security.mixed_content.block_active_content | boolean | true
4271 | If false, mixed active content (HTTP and HTTPS) is not blocked.
4272 | security.osclientcerts.autoload | boolean | false
4273 | If true, client certificates are loaded from the operating system certificate store.
4274 | security.ssl.errorReporting.enabled | boolean | true
4275 | If false, SSL errors cannot be sent to Mozilla.
4276 | security.tls.enable_0rtt_data | boolean | true
4277 | If false, TLS early data is turned off (Firefox 93, Firefox 91.2, Firefox 78.15).
4278 | security.tls.hello_downgrade_check | boolean | true
4279 | If false, the TLS 1.3 downgrade check is disabled.
4280 | security.tls.version.enable-deprecated | boolean | false
4281 | If true, browser will accept TLS 1.0. and TLS 1.1 (Firefox 86, Firefox 78.8).
4282 | security.warn_submit_secure_to_insecure | boolean | true
4283 | If false, no warning is shown when submitting a form from https to http.
4286 Using the preference as the key, set the `Value` to the corresponding preference value.
4288 `Status` can be "default", "locked", "user" or "clear"
4290 Default preferences can be modified by the user.
4292 If a value is locked, it is also set as the default.
4294 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```.
4296 User preferences persist even if the policy is removed, so if you need to remove them, you should use the clear policy.
4298 See the examples below for more detail.
4300 IMPORTANT: Make sure you're only setting a particular preference using this mechanism and not some other way.
