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`.

879 ### Certificates | Install
881 Install certificates into the Firefox certificate store. If only a filename is specified, Firefox searches for the file in the following locations:
884 - %USERPROFILE%\AppData\Local\Mozilla\Certificates
885 - %USERPROFILE%\AppData\Roaming\Mozilla\Certificates
887 - /Library/Application Support/Mozilla/Certificates
888 - ~/Library/Application Support/Mozilla/Certificates
890 - /usr/lib/mozilla/certificates
891 - /usr/lib64/mozilla/certificates
892 - ~/.mozilla/certificates
894 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.
896 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.
898 Certificates are installed using the trust string `CT,CT,`.
900 Binary (DER) and ASCII (PEM) certificates are both supported.

2512 Control the installation, uninstallation and locking of extensions.
2514 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.
2516 `Install` is a list of URLs or native paths for extensions to be installed.
2518 `Uninstall` is a list of extension IDs that should be uninstalled if found.
2520 `Locked` is a list of extension IDs that the user cannot disable or uninstall.

2594 ### ExtensionSettings
2595 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.
2597 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.
2599 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).
2601 The configuration for each extension is another dictionary that can contain the fields documented below.
2603 | Name | Description |
2605 | `installation_mode` | Maps to a string indicating the installation mode for the extension. The valid strings are `allowed`,`blocked`,`force_installed`, and `normal_installed`.
2606 | `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.
2607 | `blocked`| Blocks installation of the extension and removes it from the device if already installed.
2608 | `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.
2609 | `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.
2610 | `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.
2611 | `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.
2612 | `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.
2613 | `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.
2614 | `restricted_domains` | An array of domains on which content scripts can't be run. This setting can be used only for the default configuration.
2615 | `updates_disabled` | (Firefox 89, Firefox ESR 78.11) Boolean that indicates whether or not to disable automatic updates for an individual extension.
2617 **Compatibility:** Firefox 69, Firefox ESR 68.1 (As of Firefox 85, Firefox ESR 78.7, installing a theme makes it the default.)\

2915 ### GoToIntranetSiteForSingleWordEntryInAddressBar
2916 Whether to always go through the DNS server before sending a single word search string to a search engine.
2918 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.
2920 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.
2922 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.
2924 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`.
2926 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`.

2961 Configure default application handlers. This policy is based on the internal format of `handlers.json`.
2963 You can configure handlers based on a mime type (`mimeTypes`), a file's extension (`extensions`), or a protocol (`schemes`).
2965 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.
2967 | Name | Description |
2969 | `action`| Can be either `saveToDisk`, `useHelperApp`, `useSystemDefault`.
2970 | `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.
2971 | `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.
2972 | `name` | The display name of the handler (might not be used).
2973 | `path`| The native path to the executable to be used.
2974 | `uriTemplate`| A url to a web based application handler. The URL must be https and contain a %s to be used for substitution.

4037 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.
4039 `Allow` is a list of origins where the feature is allowed.
4041 `Block` is a list of origins where the feature is not allowed.
4043 `BlockNewRequests` determines whether or not new requests can be made for the feature.
4045 `Locked` prevents the user from changing preferences for the feature.
4047 `Default` specifies the default value for Autoplay. block-audio-video is not supported on Firefox ESR 68.
4049 **Compatibility:** Firefox 62, Firefox ESR 60.2 (Autoplay added in Firefox 74, Firefox ESR 68.6, Autoplay Default/Locked added in Firefox 76, Firefox ESR 68.8, VirtualReality added in Firefox 80, Firefox ESR 78.2)\

4439 Set and lock preferences.
4441 **NOTE** On Windows, in order to use this policy, you must clear all settings in the old **Preferences (Deprecated)** section.
4443 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.
4445 Preferences that start with the following prefixes are supported:
4448 app.update.* (Firefox 86, Firefox 78.8)
4450 datareporting.policy.
4453 general.autoScroll (Firefox 83, Firefox ESR 78.5)
4454 general.smoothScroll (Firefox 83, Firefox ESR 78.5)
4458 keyword.enabled (Firefox 95, Firefox ESR 91.4)
4463 pdfjs. (Firefox 84, Firefox ESR 78.6)
4466 signon. (Firefox 83, Firefox ESR 78.5)
4467 spellchecker. (Firefox 84, Firefox ESR 78.6)
4468 toolkit.legacyUserProfileCustomizations.stylesheets (Firefox 95, Firefox ESR 91.4)
4472 as well as the following security preferences:
4473 | Preference | Type | Default
4475 | security.default_personal_cert | string | Ask Every Time
4476 | If set to Select Automatically, Firefox automatically chooses the default personal certificate.
4477 | security.insecure_connection_text.enabled | bool | false
4478 | If set to true, adds the words "Not Secure" for insecure sites.
4479 | security.insecure_connection_text.pbmode.enabled | bool | false
4480 | If set to true, adds the words "Not Secure" for insecure sites in private browsing.
4481 | security.insecure_field_warning.contextual.enabled | bool | true
4482 | If set to false, remove the warning for inscure login fields.
4483 | security.mixed_content.block_active_content | boolean | true
4484 | If false, mixed active content (HTTP and HTTPS) is not blocked.
4485 | security.osclientcerts.autoload | boolean | false
4486 | If true, client certificates are loaded from the operating system certificate store.
4487 | security.ssl.errorReporting.enabled | boolean | true
4488 | If false, SSL errors cannot be sent to Mozilla.
4489 | security.tls.enable_0rtt_data | boolean | true
4490 | If false, TLS early data is turned off (Firefox 93, Firefox 91.2, Firefox 78.15).
4491 | security.tls.hello_downgrade_check | boolean | true
4492 | If false, the TLS 1.3 downgrade check is disabled.
4493 | security.tls.version.enable-deprecated | boolean | false
4494 | If true, browser will accept TLS 1.0. and TLS 1.1 (Firefox 86, Firefox 78.8).
4495 | security.warn_submit_secure_to_insecure | boolean | true
4496 | If false, no warning is shown when submitting a form from https to http.
4499 Using the preference as the key, set the `Value` to the corresponding preference value.
4501 `Status` can be "default", "locked", "user" or "clear"
4503 * `"default"`: Read/Write: Settings appear as default even if factory default differs.
4504 * `"locked"`: Read-Only: Settings appear as default even if factory default differs.
4505 * `"user"`: Read/Write: Settings appear as changed if it differs from factory default.
4506 * `"clear"`: Read/Write: `Value` has no effect. Resets to factory defaults on each startup.
4508 `"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```.
4510 `"user"` preferences persist even if the policy is removed, so if you need to remove them, you should use the clear policy.
4512 See the examples below for more detail.
4514 IMPORTANT: Make sure you're only setting a particular preference using this mechanism and not some other way.
