These policies are in active development and so might contain changes that do not work with current versions of Firefox.
You should use the officially released versions if you are deploying changes.
Policies can be specified using the Group Policy templates on Windows, Intune on Windows, configuration profiles on macOS, 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.

Install certificates into the Firefox certificate store. If only a filename is specified, Firefox searches for the file in the following locations:
- Windows
- %USERPROFILE%\AppData\Local\Mozilla\Certificates
- %USERPROFILE%\AppData\Roaming\Mozilla\Certificates
- macOS
- /Library/Application Support/Mozilla/Certificates
- ~/Library/Application Support/Mozilla/Certificates
- Linux
- /usr/lib/mozilla/certificates
- /usr/lib64/mozilla/certificates
- ~/.mozilla/certificates
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.
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.
Certificates are installed using the trust string CT,CT,.
Binary (DER) and ASCII (PEM) certificates are both supported.

Configure tracking protection.
If this policy is not configured, tracking protection is not enabled by default in the browser, but it is enabled by default in private browsing and the user can change it.
If Value is set to false, tracking protection is disabled and locked in both the regular browser and private browsing.
If Value is set to true, tracking protection is enabled by default in both the regular browser and private browsing and the Locked value determines whether or not a user can change it.
If Cryptomining is set to true, cryptomining scripts on websites are blocked.
If Fingerprinting is set to true, fingerprinting scripts on websites are blocked.

Control the installation, uninstallation and locking of extensions.
While this policy is not technically deprecated, it is recommended that you use the 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.
Install is a list of URLs or native paths for extensions to be installed.
Uninstall is a list of extension IDs that should be uninstalled if found.
Locked is a list of extension IDs that the user cannot disable or uninstall.

Manage all aspects of extensions. This policy is based heavily on the Chrome policy of the same name.
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.
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.
The configuration for each extension is another dictionary that can contain the fields documented below.
| Name | Description |
|---|---|
installation_mode |
Maps to a string indicating the installation mode for the extension. The valid strings are allowed,blocked,force_installed, and normal_installed. |
        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. |
        blocked |
Blocks installation of the extension and removes it from the device if already installed. |
        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. |
        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. |
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. 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. |
install_sources |
A list of sources from which installing extensions is allowed using URL match patterns. 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. |
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. |
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. |
restricted_domains |
An array of domains on which content scripts can't be run. This setting can be used only for the default configuration. |
updates_disabled |
(Firefox 89, Firefox ESR 78.11) Boolean that indicates whether or not to disable automatic updates for an individual extension. |
Compatibility: Firefox 69, Firefox ESR 68.1 (As of Firefox 85, Firefox ESR 78.7, installing a theme makes it the default.)

Whether to always go through the DNS server before sending a single word search string to a search engine.
If the site exists, it will navigate to the website. If the intranet responds with a 404, the page will show a 404. If the intranet does not respond, the browser will attempt a search.
The second result in the URL bar will be a search result to allow users to conduct a web search exactly as it was entered.
If instead you would like to enable the ability to have your domain appear as a valid URL and to disallow the browser from ever searching that term using the first result that matches it, add the pref browser.fixup.domainwhitelist.YOUR_DOMAIN (where YOUR_DOMAIN is the name of the domain you'd like to add), and set the pref to true. The URL bar will then suggest YOUR_DOMAIN when the user fully types YOUR_DOMAIN. If the user attempts to load that domain and it fails to load, it will show an "Unable to connect" error page.
You can also whitelist a domain suffix that is not part of the Public Suffix List by adding the pref browser.fixup.domainsuffixwhitelist.YOUR_DOMAIN_SUFFIX with a value of true.
Additionally, if you want users to see a "Did you mean to go to 'YOUR_DOMAIN'" prompt below the URL bar if they land on a search results page instead of an intranet domain that provides a response, set the pref browser.urlbar.dnsResolveSingleWordsAfterSearch to 1. Enabling this will cause the browser to commit a DNS check after every single word search. If the browser receives a response from the intranet, a prompt will ask the user if they'd like to instead navigate to YOUR_DOMAIN. If the user presses the yes button, browser.fixup.domainwhitelist.YOUR_DOMAIN will be set to true.

Configure default application handlers. This policy is based on the internal format of handlers.json.
You can configure handlers based on a mime type (mimeTypes), a file's extension (extensions), or a protocol (schemes).
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.
| Name | Description |
|---|---|
action |
Can be either saveToDisk, useHelperApp, useSystemDefault. |
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. |
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. |
        name |
The display name of the handler (might not be used). |
        path |
The native path to the executable to be used. |
        uriTemplate |
A url to a web based application handler. The URL must be https and contain a %s to be used for substitution. |

Switch to manual updates only.
If this policy is enabled:
- The user will never be prompted to install updates
- 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.
- The update UI will work as expected, unlike when using DisableAppUpdate.
This policy is primarily intended for advanced end users, not for enterprises.

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.
Allow is a list of origins where the feature is allowed.
Block is a list of origins where the feature is not allowed.
BlockNewRequests determines whether or not new requests can be made for the feature.
Locked prevents the user from changing preferences for the feature.

Set and lock preferences.
NOTE On Windows, in order to use this policy, you must clear all settings in the old Preferences (Deprecated) section.
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.
Preferences that start with the following prefixes are supported:
accessibility.
app.update.* (Firefox 86, Firefox 78.8)
browser.
datareporting.policy.
dom.
extensions.
general.autoScroll (Firefox 83, Firefox ESR 78.5)
general.smoothScroll (Firefox 83, Firefox ESR 78.5)
geo.
gfx.
intl.
keyword.enabled (Firefox 95, Firefox ESR 91.4)
layers.
layout.
media.
network.
pdfjs. (Firefox 84, Firefox ESR 78.6)
places.
print.
signon. (Firefox 83, Firefox ESR 78.5)
spellchecker. (Firefox 84, Firefox ESR 78.6)
toolkit.legacyUserProfileCustomizations.stylesheets (Firefox 95, Firefox ESR 91.4)
ui.
widget.
as well as the following security preferences:
| Preference | Type | Default |

| security.default_personal_cert | string | Ask Every Time |
| Â Â Â Â If set to Select Automatically, Firefox automatically chooses the default personal certificate. | ||
| security.insecure_connection_text.enabled | bool | false |

| security.insecure_connection_text.pbmode.enabled | bool | false |
| Â Â Â Â If set to true, adds the words "Not Secure" for insecure sites in private browsing. | ||
| security.insecure_field_warning.contextual.enabled | bool | true |
| Â Â Â Â If set to false, remove the warning for inscure login fields. | ||
| security.mixed_content.block_active_content | boolean | true |

| security.tls.hello_downgrade_check | boolean | true |
| Â Â Â Â If false, the TLS 1.3 downgrade check is disabled. | ||
| security.tls.version.enable-deprecated | boolean | false |
| Â Â Â Â If true, browser will accept TLS 1.0. and TLS 1.1 (Firefox 86, Firefox 78.8). | ||
| security.warn_submit_secure_to_insecure | boolean | true |
| Â Â Â Â If false, no warning is shown when submitting a form from https to http. | ||

Using the preference as the key, set the Value to the corresponding preference value.
Status can be "default", "locked", "user" or "clear"
"default": Read/Write: Settings appear as default even if factory default differs."locked": Read-Only: Settings appear as default even if factory default differs."user": Read/Write: Settings appear as changed if it differs from factory default."clear": Read/Write:Valuehas no effect. Resets to factory defaults on each startup.
"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.
"user" preferences persist even if the policy is removed, so if you need to remove them, you should use the clear policy.
See the examples below for more detail.
IMPORTANT: Make sure you're only setting a particular preference using this mechanism and not some other way.

Configure proxy settings. These settings correspond to the connection settings in Firefox preferences. To specify ports, append them to the hostnames with a colon (:).
Unless you lock this policy, changes the user already has in place will take effect.
Mode is the proxy method being used.
Locked is whether or not proxy settings can be changed.
HTTPProxy is the HTTP proxy server.
UseHTTPProxyForAllProtocols is whether or not the HTTP proxy should be used for all other proxies.
SSLProxy is the SSL proxy server.
FTPProxy is the FTP proxy server.
SOCKSProxy is the SOCKS proxy server
SOCKSVersion is the SOCKS version (4 or 5)
Passthrough is list of hostnames or IP addresses that will not be proxied. Use <local> to bypass proxying for all hostnames which do not contain periods.
AutoConfigURL is a URL for proxy configuration (only used if Mode is autoConfig).
AutoLogin means do not prompt for authentication if password is saved.
UseProxyForDNS to use proxy DNS when using SOCKS v5.
