   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 ```

 608 ### AutoLaunchProtocolsFromOrigins
 609 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.
 610
 611 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.
 612
 613 The schema is:
 614 ```
 615 {
 616  "items": {
 617   "properties": {
 618    "allowed_origins": {

 705
 706 If set to false, the application will not try to install updates when the application is not running.
 707
 708 If you have disabled updates via `DisableAppUpdate` or disabled automatic updates via `AppAutoUpdate`, this policy has no effect.

1070 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.
1071
1072 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.
1073
1074 Certificates are installed using the trust string `CT,CT,`.
1075
1076 Binary (DER) and ASCII (PEM) certificates are both supported.

2782 ### Extensions
2783 Control the installation, uninstallation and locking of extensions.
2784
2785 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.
2786
2787 This method will be deprecated in the near future.
2788
2789 `Install` is a list of URLs or native paths for extensions to be installed.
2790
2791 `Uninstall` is a list of extension IDs that should be uninstalled if found.
2792
2793 `Locked` is a list of extension IDs that the user cannot disable or uninstall.

2867 ### ExtensionSettings
2868 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.
2869
2870 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.
2871
2872 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).
2873
2874 The configuration for each extension is another dictionary that can contain the fields documented below.
2875
2876 | Name | Description |
2877 | --- | --- |
2878 | `installation_mode` | Maps to a string indicating the installation mode for the extension. The valid strings are `allowed`,`blocked`,`force_installed`, and `normal_installed`.
2879 | &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.
2880 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`blocked`| Blocks installation of the extension and removes it from the device if already installed.
2881 | &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.
2882 | &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.
2883 | `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.
2884 | `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.
2885 | `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.
2886 | `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.
2887 | `restricted_domains` | An array of domains on which content scripts can't be run. This setting can be used only for the default configuration.
2888 | `updates_disabled` | (Firefox 89, Firefox ESR 78.11) Boolean that indicates whether or not to disable automatic updates for an individual extension.
2889 | `default_area` | (Firefox 113) String that indicates where to place the extension icon by default. Possible values are `navbar` and `menupanel`.
2890 | `temporarily_allow_weak_signatures`| (Firefox 127) A boolean that indicates whether to allow installing extensions signed using deprecated signature algorithms.
2891
2892 **Compatibility:** Firefox 69, Firefox ESR 68.1 (As of Firefox 85, Firefox ESR 78.7, installing a theme makes it the default.)\

3189 ### GoToIntranetSiteForSingleWordEntryInAddressBar
3190 Whether to always go through the DNS server before sending a single word search string to a search engine.
3191
3192 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.
3193
3194 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.
3195
3196 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.
3197
3198 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`.
3199
3200 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`.

3234 ### Handlers
3235 Configure default application handlers. This policy is based on the internal format of `handlers.json`.
3236
3237 You can configure handlers based on a mime type (`mimeTypes`), a file's extension (`extensions`), or a protocol (`schemes`).
3238
3239 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.
3240
3241 | Name | Description |
3242 | --- | --- |
3243 | `action`| Can be either `saveToDisk`, `useHelperApp`, `useSystemDefault`.
3244 | `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.
3245 | `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.
3246 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`name` | The display name of the handler (might not be used).
3247 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`path`| The native path to the executable to be used.
3248 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`uriTemplate`| A url to a web based application handler. The URL must be https and contain a %s to be used for substitution.

3994 ### ManualAppUpdateOnly
3995
3996 Switch to manual updates only.
3997
3998 If this policy is enabled:
3999  1. The user will never be prompted to install updates
4000  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.
4001  3. The update UI will work as expected, unlike when using DisableAppUpdate.
4002
4003 This policy is primarily intended for advanced end users, not for enterprises, but it is available via GPO.

4364 ### PDFjs
4365 Disable or configure PDF.js, the built-in PDF viewer.
4366
4367 If `Enabled` is set to false, the built-in PDF viewer is disabled.
4368
4369 If `EnablePermissions` is set to true, the built-in PDF viewer will honor document permissions like preventing the copying of text.
4370
4371 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.

4415 ### Permissions
4416 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.
4417
4418 `Allow` is a list of origins where the feature is allowed.
4419
4420 `Block` is a list of origins where the feature is not allowed.
4421
4422 `BlockNewRequests` determines whether or not new requests can be made for the feature.
4423
4424 `Locked` prevents the user from changing preferences for the feature.
4425
4426 `Default` specifies the default value for Autoplay. block-audio-video is not supported on Firefox ESR 68.
4427
4428 **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)\
4429 **CCK2 Equivalent:** N/A\

4914 | &nbsp;&nbsp;&nbsp;&nbsp;If true, client certificates are loaded from the operating system certificate store.
4915 | security.OCSP.enabled | integer | 1
4916 | &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.

4918 | &nbsp;&nbsp;&nbsp;&nbsp; If true, if an OCSP request times out, the connection fails.
4919 | security.osclientcerts.assume_rsa_pss_support | boolean | true
4920 | &nbsp;&nbsp;&nbsp;&nbsp; If false, we don't assume an RSA key can do RSA-PSS. (Firefox 114, Firefox ESR 102.12)
4921 | security.ssl.enable_ocsp_stapling | boolean | true
4922 | &nbsp;&nbsp;&nbsp;&nbsp; If false, OCSP stapling is not enabled.

4934 | &nbsp;&nbsp;&nbsp;&nbsp;If false, no warning is shown when submitting a form from https to http.
4935
4936 Using the preference as the key, set the `Value` to the corresponding preference value.
4937
4938 `Status` can be "default", "locked", "user" or "clear"
4939
4940 * `"default"`: Read/Write: Settings appear as default even if factory default differs.
4941 * `"locked"`: Read-Only: Settings appear as default even if factory default differs.
4942 * `"user"`: Read/Write: Settings appear as changed if it differs from factory default.
4943 * `"clear"`: Read/Write: `Value` has no effect. Resets to factory defaults on each startup.
4944
4945 `"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```.
4946
4947 `"user"` preferences persist even if the policy is removed, so if you need to remove them, you should use the clear policy.
4948
4949 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.
4950
4951 See the examples below for more detail.
4952
4953 IMPORTANT: Make sure you're only setting a particular preference using this mechanism and not some other way.

5058 ### PrimaryPassword
5059 Require or prevent using a primary (formerly master) password.
5060
5061 If this value is true, a primary password is required. If this value is false, it works the same as if [`DisableMasterPasswordCreation`](#disablemasterpasswordcreation) was true and removes the primary password functionality.
5062
5063 If both DisableMasterPasswordCreation and PrimaryPassword are used, DisableMasterPasswordCreation takes precedent.

5444 Clear data on shutdown. Choose from Cache, Cookies, Download History, Form & Search History, Browsing History, Active Logins, Site Preferences and Offline Website Data.

5446 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.

6380 ### WebsiteFilter
6381 Block websites from being visited. The parameters take an array of Match Patterns, as documented in https://developer.mozilla.org/en-US/Add-ons/WebExtensions/Match_patterns.
6382 The arrays are limited to 1000 entries each.
6383
6384 If you want to block all URLs, you can use `<all_urls>` or `*://*/*`. You can't have just a `*` on the right side.
6385
6386 For specific protocols, use `https://*/*` or `http://*/*`.
6387
6388 As of Firefox 83 and Firefox ESR 78.5, file URLs are supported.
