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`.
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:
-
```
{
"policies": {
}
}
```
+Note: The `policies.json` must use the UTF-8 encoding.

+### ContentAnalysis
+Configure Firefox to use an agent for Data Loss Prevention (DLP) that is compatible with the [Google Chrome Content Analysis Connector Agent SDK](https://github.com/chromium/content_analysis_sdk).
+
+`AgentName` is the name of the DLP agent. This is used in dialogs and notifications about DLP operations. The default is "A DLP Agent".
+
+`AgentTimeout` is the timeout in number of seconds after a DLP request is sent to the agent. After this timeout, the request will be denied unless `DefaultResult` is set to 1 or 2. The default is 30.
+
+`AllowUrlRegexList` is a space-separated list of regular expressions that indicates URLs for which DLP operations will always be allowed without consulting the agent. The default is "^about:(?!blank|srcdoc).*", meaning that any pages that start with "about:" will be exempt from DLP except for "about:blank" and "about:srcdoc", as these can be controlled by web content.
+
+`BypassForSameTabOperations` indicates whether Firefox will automatically allow DLP requests whose data comes from the same tab and frame - for example, if data is copied to the clipboard and then pasted on the same page. The default is false.
+
+`ClientSignature` indicates the required signature of the DLP agent connected to the pipe. If this is a non-empty string and the DLP agent does not have a signature with a Subject Name that exactly matches this value, Firefox will not connect to the pipe. The default is the empty string.
+
+`DefaultResult` indicates the desired behavior for DLP requests if there is a problem connecting to the DLP agent. The default is 0.
+
+| Value | Description
+| --- | --- |
+| 0 | Deny the request (default)
+| 1 | Warn the user and allow them to choose whether to allow or deny
+| 2 | Allow the request
+
+`DenyUrlRegexList` is a space-separated list of regular expressions that indicates URLs for which DLP operations will always be denied without consulting the agent. The default is the empty string.
+
+`Enabled` indicates whether Firefox should use DLP. Note that if this value is true and no DLP agent is running, all DLP requests will be denied unless `DefaultResult` is set to 1 or 2.
+
+`IsPerUser` indicates whether the pipe the DLP agent has created is per-user or per-system. The default is true, meaning per-user.
+
+`PipePathName` is the name of the pipe the DLP agent has created and Firefox will connect to. The default is "path_user".
+
+`ShowBlockedResult` indicates whether Firefox should show a notification when a DLP request is denied. The default is true.
+
+**Compatibility:** Firefox 130\
+**CCK2 Equivalent:** N/A\
+**Preferences Affected:** `browser.contentanalysis.agent_name`, `browser.contentanalysis.agent_timeout`, `browser.contentanalysis.allow_url_regex_list`, `browser.contentanalysis.bypass_for_same_tab_operations`, `browser.contentanalysis.client_signature`, `browser.contentanalysis.default_result`, `browser.contentanalysis.deny_url_regex_list`, `browser.contentanalysis.enabled`, `browser.contentanalysis.is_per_user`, `browser.contentanalysis.pipe_path_name`, `browser.contentanalysis.show_blocked_result`
