   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:
   4
   5 ```
   6 {
   7   "policies": {
   8     "Authentication": {
   9       "SPNEGO": ["mydomain.com", "https://myotherdomain.com"]
  10     }
  11     "Authentication_Comment": "These domains are required for us"
  12   }
  13 }
  14 ```

 604 ### AutoLaunchProtocolsFromOrigins
 605 Define a list of external protocols that can be used from listed origins without prompting the user. The origin is the scheme plus the hostname.
 606
 607 The syntax of this policy is exactly the same as the [Chrome AutoLaunchProtocolsFromOrigins policy](https://cloud.google.com/docs/chrome-enterprise/policies/?policy=AutoLaunchProtocolsFromOrigins) except that you can only use valid origins (not just hostnames). This also means that you cannot specify an asterisk for all origins.
 608
 609 The schema is:
 610 ```
 611 {
 612  "items": {
 613   "properties": {
 614    "allowed_origins": {

1066 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.
1067
1068 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.
1069
1070 Certificates are installed using the trust string `CT,CT,`.
1071
1072 Binary (DER) and ASCII (PEM) certificates are both supported.

2681 This policy is based on the [Chrome policy](https://chromeenterprise.google/policies/#ExemptDomainFileTypePairsFromFileTypeDownloadWarnings) of the same name.
2682
2683 Important: The documentation for the policy for both Edge and Chrome is incorrect. The ```domains``` value must be a domain, not a URL pattern. Also, we do not support using ```*``` to mean all domains.

2743 ### Extensions
2744 Control the installation, uninstallation and locking of extensions.
2745
2746 We strongly recommend 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.
2747
2748 This method will be deprecated in the near future.
2749
2750 `Install` is a list of URLs or native paths for extensions to be installed.
2751
2752 `Uninstall` is a list of extension IDs that should be uninstalled if found.
2753
2754 `Locked` is a list of extension IDs that the user cannot disable or uninstall.

2828 ### ExtensionSettings
2829 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.
2830
2831 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.
2832
2833 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).
2834
2835 The configuration for each extension is another dictionary that can contain the fields documented below.
2836
2837 | Name | Description |
2838 | --- | --- |
2839 | `installation_mode` | Maps to a string indicating the installation mode for the extension. The valid strings are `allowed`,`blocked`,`force_installed`, and `normal_installed`.
2840 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`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.
2841 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`blocked`| Blocks installation of the extension and removes it from the device if already installed.
2842 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`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.
2843 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`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.
2844 | `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.
2845 | `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.
2846 | `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.
2847 | `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.
2848 | `restricted_domains` | An array of domains on which content scripts can't be run. This setting can be used only for the default configuration.
2849 | `updates_disabled` | (Firefox 89, Firefox ESR 78.11) Boolean that indicates whether or not to disable automatic updates for an individual extension.
2850 | `default_area` | (Firefox 113) String that indicates where to place the extension icon by default. Possible values are `navbar` and `menupanel`.
2851

3149 ### GoToIntranetSiteForSingleWordEntryInAddressBar
3150 Whether to always go through the DNS server before sending a single word search string to a search engine.
3151
3152 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.
3153
3154 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.
3155
3156 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.
3157
3158 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`.
3159
3160 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`.

3194 ### Handlers
3195 Configure default application handlers. This policy is based on the internal format of `handlers.json`.
3196
3197 You can configure handlers based on a mime type (`mimeTypes`), a file's extension (`extensions`), or a protocol (`schemes`).
3198
3199 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.
3200
3201 | Name | Description |
3202 | --- | --- |
3203 | `action`| Can be either `saveToDisk`, `useHelperApp`, `useSystemDefault`.

3709 ### ManagedBookmarks
3710 Configures a list of bookmarks managed by an administrator that cannot be changed by the user.
3711
3712 The bookmarks are only added as a button on the personal toolbar. They are not in the bookmarks folder.
3713
3714 The syntax of this policy is exactly the same as the [Chrome ManagedBookmarks policy](https://cloud.google.com/docs/chrome-enterprise/policies/?policy=ManagedBookmarks). The schema is:
3715 ```
3716 {
3717  "items": {
3718   "id": "BookmarkType",
3719   "properties": {
3720    "children": {

3868 ### ManualAppUpdateOnly
3869
3870 Switch to manual updates only.
3871
3872 If this policy is enabled:
3873  1. The user will never be prompted to install updates
3874  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.
3875  3. The update UI will work as expected, unlike when using DisableAppUpdate.
3876
3877 This policy is primarily intended for advanced end users, not for enterprises, but it is available via GPO.

4244 If `EnablePermissions` is set to true, the built-in PDF viewer will honor document permissions like preventing the copying of text.
4245
4246 Note: DisableBuiltinPDFViewer has not been deprecated. You can either continue to use it, or switch to using PDFjs->Enabled to disable the built-in PDF viewer. This new permission was added because we needed a place for PDFjs->EnabledPermissions.

4290 ### Permissions
4291 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.
4292
4293 `Allow` is a list of origins where the feature is allowed.
4294
4295 `Block` is a list of origins where the feature is not allowed.
4296
4297 `BlockNewRequests` determines whether or not new requests can be made for the feature.
4298
4299 `Locked` prevents the user from changing preferences for the feature.
4300
4301 `Default` specifies the default value for Autoplay. block-audio-video is not supported on Firefox ESR 68.
4302
4303 **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)\
4304 **CCK2 Equivalent:** N/A\
4305 **Preferences Affected:** `permissions.default.camera`, `permissions.default.microphone`, `permissions.default.geo`, `permissions.default.desktop-notification`, `media.autoplay.default`, `permissions.default.xr`

4753 | security.osclientcerts.autoload | boolean | false
4754 | &nbsp;&nbsp;&nbsp;&nbsp;If true, client certificates are loaded from the operating system certificate store.
4755 | security.OCSP.enabled | integer | 1
4756 | &nbsp;&nbsp;&nbsp;&nbsp;If 0, do not fetch OCSP. If 1, fetch OCSP for DV and EV certificates. If 2, fetch OCSP only for EV certificates.
4757 | security.OCSP.require | boolean | false
4758 | &nbsp;&nbsp;&nbsp;&nbsp; If true, if an OCSP request times out, the connection fails.
4759 | security.osclientcerts.assume_rsa_pss_support | boolean | true
4760 | &nbsp;&nbsp;&nbsp;&nbsp; If false, we don't assume an RSA key can do RSA-PSS. (Firefox 114, Firefox ESR 102.12)
4761 | security.ssl.enable_ocsp_stapling | boolean | true
4762 | &nbsp;&nbsp;&nbsp;&nbsp; If false, OCSP stapling is not enabled.

4764 | &nbsp;&nbsp;&nbsp;&nbsp;If false, SSL errors cannot be sent to Mozilla.
4765 | security.ssl.require_safe_negotiation | boolean | false
4766 | &nbsp;&nbsp;&nbsp;&nbsp;If true, Firefox will only negotiate TLS connections with servers that indicate they support secure renegotiation. (Firefox 118, Firefox ESR 115.3)
4767 | security.tls.enable_0rtt_data | boolean | true
4768 | &nbsp;&nbsp;&nbsp;&nbsp;If false, TLS early data is turned off. (Firefox 93, Firefox 91.2, Firefox 78.15)
4769 | security.tls.hello_downgrade_check | boolean | true
4770 | &nbsp;&nbsp;&nbsp;&nbsp;If false, the TLS 1.3 downgrade check is disabled.
4771 | security.tls.version.enable-deprecated | boolean | false
4772 | &nbsp;&nbsp;&nbsp;&nbsp;If true, browser will accept TLS 1.0. and TLS 1.1. (Firefox 86, Firefox 78.8)
4773 | security.warn_submit_secure_to_insecure | boolean | true
4774 | &nbsp;&nbsp;&nbsp;&nbsp;If false, no warning is shown when submitting a form from https to http.
4775
4776 Using the preference as the key, set the `Value` to the corresponding preference value.
4777
4778 `Status` can be "default", "locked", "user" or "clear"
4779
4780 * `"default"`: Read/Write: Settings appear as default even if factory default differs.
4781 * `"locked"`: Read-Only: Settings appear as default even if factory default differs.
4782 * `"user"`: Read/Write: Settings appear as changed if it differs from factory default.
4783 * `"clear"`: Read/Write: `Value` has no effect. Resets to factory defaults on each startup.
4784
4785 `"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```.
4786
4787 `"user"` preferences persist even if the policy is removed, so if you need to remove them, you should use the clear policy.
4788
4789 You can also set the `Type` starting in Firefox 123 and Firefox ESR 115.8. It can be `number`, `boolean` or `string`. This is especially useful if you are seeing 0 or 1 values being converted to booleans when set as user preferences.
4790
4791 See the examples below for more detail.
4792
4793 IMPORTANT: Make sure you're only setting a particular preference using this mechanism and not some other way.

5030
5031 `AutoConfigURL` is a  URL for proxy configuration (only used if Mode is autoConfig).
5032
5033 `AutoLogin` means do not prompt for authentication if password is saved.

5283 ### SanitizeOnShutdown (Selective)
5284 Clear data on shutdown. Choose from Cache, Cookies, Download History, Form & Search History, Browsing History, Active Logins, Site Preferences and Offline Website Data.
5285
5286 Previously, these values were always locked. Starting with Firefox 74 and Firefox ESR 68.6, you can use the `Locked` option to either keep the values unlocked (set it to false), or lock only the values you set (set it to true). If you want the old behavior of locking everything, do not set `Locked` at all.
