[policy-templates.git] / README.md

**IMPORTANT**: This file is in active development along with the policies in Firefox. Make sure to check the compatibility section to see if a policy is available in a specific version of Firefox. To get the policy information that corresponds to a specific release, go to https://github.com/mozilla/policy-templates/releases.

Policies can be specified using the Group Policy templates on Windows (https://github.com/mozilla/policy-templates/tree/master/windows), 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.

### Certificates

### Certificates | ImportEnterpriseRoots

Trust certificates that have been added to the operating system certificate store by a user or administrator.

See https://support.mozilla.org/kb/setting-certificate-authorities-firefox for more detail.

**Compatibility:** Firefox 60, Firefox ESR 60 (macOS support in Firefox 63, Firefox ESR 68)\
**CCK2 Equivalent:** N/A\
**Preferences Affected:** `security.enterprise_roots.enabled`

#### Windows
```
Software\Policies\Mozilla\Firefox\Certificates\ImportEnterpriseRoots = 0x1 | 0x0
```
#### macOS
```
<dict>
  <key>Certificates</key>

    <key>ImportEnterpriseRoots</key>

</dict>
```
#### JSON
```
{
  "policies": {
    "Certificates": {
      "ImportEnterpriseRoots": true | false
    }
  }
}
```
### Certificates | Install

Install certificates into the Firefox certificate store. If only a filename is specified, Firefox searches for the file in the following locations:

- Windows
  - %USERPROFILE%\AppData\Local\Mozilla\Certificates
  - %USERPROFILE%\AppData\Roaming\Mozilla\Certificates
- macOS
  - /Library/Application Support/Mozilla/Certificates
  - ~/Library/Application Support/Mozilla/Certificates
- Linux
  - /usr/lib/mozilla/certificates
  - /usr/lib64/mozilla/certificates
  - ~/.mozilla/certificates

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.

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.

Certificates are installed using the trust string `CT,CT,`.

Binary (DER) and ASCII (PEM) certificates are both supported.

**Compatibility:** Firefox 64, Firefox ESR 64\
**CCK2 Equivalent:** `certs.ca`\
**Preferences Affected:** N/A

#### Windows
```
Software\Policies\Mozilla\Firefox\Certificates\Install\1 = "cert1.der"

### Cookies

`Allow` is a list of origins (not domains) where cookies are always allowed. You must include http or https.

`Default` determines whether cookies are accepted at all.

`AcceptThirdParty` determines how third-party cookies are handled.

`ExpireAtSessionEnd` determines when cookies expire.

`RejectTracker` only rejects cookies for trackers.
