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.

`"user"` preferences persist even if the policy is removed, so if you need to remove them, you should use the clear policy.
+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.

See the examples below for more detail.
IMPORTANT: Make sure you're only setting a particular preference using this mechanism and not some other way.
