1 Firefox 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`.
3 Unfortunately, JSON files do not support comments, but you can add extra entries to the JSON to use as comments. You will see an error in about:policies, but the policies will still work properly. For example:
9 "SPNEGO": ["mydomain.com", "https://myotherdomain.com"]
11 "Authentication_Comment": "These domains are required for us"

887 ### Certificates | ImportEnterpriseRoots
889 Trust certificates that have been added to the operating system certificate store by a user or administrator.
891 Note: This policy only works on Windows and macOS. For Linux discussion, see [bug 1600509](https://bugzilla.mozilla.org/show_bug.cgi?id=1600509).
893 See https://support.mozilla.org/kb/setting-certificate-authorities-firefox for more detail.

932 ### Certificates | Install
934 Install certificates into the Firefox certificate store. If only a filename is specified, Firefox searches for the file in the following locations:
937 - %USERPROFILE%\AppData\Local\Mozilla\Certificates
938 - %USERPROFILE%\AppData\Roaming\Mozilla\Certificates
940 - /Library/Application Support/Mozilla/Certificates
941 - ~/Library/Application Support/Mozilla/Certificates
943 - /usr/lib/mozilla/certificates
944 - /usr/lib64/mozilla/certificates
945 - ~/.mozilla/certificates
947 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.
949 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.
951 Certificates are installed using the trust string `CT,CT,`.
953 Binary (DER) and ASCII (PEM) certificates are both supported.

2650 Control the installation, uninstallation and locking of extensions.
2652 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.
2654 `Install` is a list of URLs or native paths for extensions to be installed.
2656 `Uninstall` is a list of extension IDs that should be uninstalled if found.
2658 `Locked` is a list of extension IDs that the user cannot disable or uninstall.

2732 ### ExtensionSettings
2733 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.
2735 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.
2737 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).
2739 The configuration for each extension is another dictionary that can contain the fields documented below.
2741 | Name | Description |
2743 | `installation_mode` | Maps to a string indicating the installation mode for the extension. The valid strings are `allowed`,`blocked`,`force_installed`, and `normal_installed`.
2744 | `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.
2745 | `blocked`| Blocks installation of the extension and removes it from the device if already installed.
2746 | `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.
2747 | `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.
2748 | `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.
2749 | `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.
2750 | `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.
2751 | `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.
2752 | `restricted_domains` | An array of domains on which content scripts can't be run. This setting can be used only for the default configuration.
2753 | `updates_disabled` | (Firefox 89, Firefox ESR 78.11) Boolean that indicates whether or not to disable automatic updates for an individual extension.
2754 | `default_area` | (Firefox 113) String that indicates where to place the extension icon by default. Possible values are `navbar` and `menupanel`.
2756 **Compatibility:** Firefox 69, Firefox ESR 68.1 (As of Firefox 85, Firefox ESR 78.7, installing a theme makes it the default.)\

3048 ### GoToIntranetSiteForSingleWordEntryInAddressBar
3049 Whether to always go through the DNS server before sending a single word search string to a search engine.
3051 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.
3053 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.
3055 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.
3057 You can also whitelist a domain suffix that is not part of the [Public Suffix List](https://publicsuffix.org/) by adding the pref `browser.fixup.domainsuffixwhitelist.YOUR_DOMAIN_SUFFIX` with a value of `true`.
3059 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`.

3094 Configure default application handlers. This policy is based on the internal format of `handlers.json`.
3096 You can configure handlers based on a mime type (`mimeTypes`), a file's extension (`extensions`), or a protocol (`schemes`).
3098 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.
3100 | Name | Description |
3102 | `action`| Can be either `saveToDisk`, `useHelperApp`, `useSystemDefault`.
3103 | `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.
3104 | `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.
3105 | `name` | The display name of the handler (might not be used).
3106 | `path`| The native path to the executable to be used.
3107 | `uriTemplate`| A url to a web based application handler. The URL must be https and contain a %s to be used for substitution.

4174 `Block` is a list of origins where the feature is not allowed.
4176 `BlockNewRequests` determines whether or not new requests can be made for the feature.

4572 Set and lock preferences.
4574 **NOTE** On Windows, in order to use this policy, you must clear all settings in the old **Preferences (Deprecated)** section in group policy.
4576 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.
4578 Preferences that start with the following prefixes are supported:
4581 app.update.* (Firefox 86, Firefox 78.8)
4583 datareporting.policy.
4586 general.autoScroll (Firefox 83, Firefox ESR 78.5)
4587 general.smoothScroll (Firefox 83, Firefox ESR 78.5)
4591 keyword.enabled (Firefox 95, Firefox ESR 91.4)
4596 pdfjs. (Firefox 84, Firefox ESR 78.6)
4599 signon. (Firefox 83, Firefox ESR 78.5)
4600 spellchecker. (Firefox 84, Firefox ESR 78.6)
4601 toolkit.legacyUserProfileCustomizations.stylesheets (Firefox 95, Firefox ESR 91.4)
4604 xpinstall.signatures.required (Firefox ESR 102.10, Firefox ESR only)
4605 xpinstall.whitelist.required (Firefox 118, Firefox ESR 115.3)
4607 as well as the following security preferences:
4609 | Preference | Type | Default
4611 | security.default_personal_cert | string | Ask Every Time
4612 | If set to Select Automatically, Firefox automatically chooses the default personal certificate.
4613 | security.insecure_connection_text.enabled | bool | false
4614 | If set to true, adds the words "Not Secure" for insecure sites.
4615 | security.insecure_connection_text.pbmode.enabled | bool | false
4616 | If set to true, adds the words "Not Secure" for insecure sites in private browsing.
4617 | security.mixed_content.block_active_content | boolean | true
4618 | If false, mixed active content (HTTP and HTTPS) is not blocked.
4619 | security.osclientcerts.autoload | boolean | false
4620 | If true, client certificates are loaded from the operating system certificate store.
4621 | security.OCSP.enabled | integer | 1
4622 | If 0, do not fetch OCSP. If 1, fetch OCSP for DV and EV certificates. If 2, fetch OCSP only for EV certificates.
4623 | security.OCSP.require | boolean | false
4624 | If true, if an OCSP request times out, the connection fails.
4625 | security.osclientcerts.assume_rsa_pss_support | boolean | true
4626 | If false, we don't assume an RSA key can do RSA-PSS. (Firefox 114, Firefox ESR 102.12)
4627 | security.ssl.enable_ocsp_stapling | boolean | true
4628 | If false, OCSP stapling is not enabled.
4629 | security.ssl.errorReporting.enabled | boolean | true
4630 | If false, SSL errors cannot be sent to Mozilla.
4631 | security.ssl.require_safe_negotiation | boolean | false
4632 | If true, Firefox will only negotiate TLS connections with servers that indicate they support secure renegotiation. (Firefox 118, Firefox ESR 115.3)
4633 | security.tls.enable_0rtt_data | boolean | true
4634 | If false, TLS early data is turned off. (Firefox 93, Firefox 91.2, Firefox 78.15)
4635 | security.tls.hello_downgrade_check | boolean | true
4636 | If false, the TLS 1.3 downgrade check is disabled.
4637 | security.tls.version.enable-deprecated | boolean | false
4638 | If true, browser will accept TLS 1.0. and TLS 1.1. (Firefox 86, Firefox 78.8)
4639 | security.warn_submit_secure_to_insecure | boolean | true
4640 | If false, no warning is shown when submitting a form from https to http.
4642 Using the preference as the key, set the `Value` to the corresponding preference value.
4644 `Status` can be "default", "locked", "user" or "clear"
4646 * `"default"`: Read/Write: Settings appear as default even if factory default differs.
4647 * `"locked"`: Read-Only: Settings appear as default even if factory default differs.
4648 * `"user"`: Read/Write: Settings appear as changed if it differs from factory default.
4649 * `"clear"`: Read/Write: `Value` has no effect. Resets to factory defaults on each startup.
4651 `"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```.
4653 `"user"` preferences persist even if the policy is removed, so if you need to remove them, you should use the clear policy.
4655 See the examples below for more detail.
4657 IMPORTANT: Make sure you're only setting a particular preference using this mechanism and not some other way.
