1 **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.
3 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.

392 ### Certificates | Install
394 Install certificates into the Firefox certificate store. If only a filename is specified, Firefox searches for the file in the following locations:
397 - %USERPROFILE%\AppData\Local\Mozilla\Certificates
398 - %USERPROFILE%\AppData\Roaming\Mozilla\Certificates
400 - /Library/Application Support/Mozilla/Certificates
401 - ~/Library/Application Support/Mozilla/Certificates
403 - /usr/lib/mozilla/certificates
404 - /usr/lib64/mozilla/certificates
405 - ~/.mozilla/certificates
407 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.
409 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.
411 Certificates are installed using the trust string `CT,CT,`.
413 Binary (DER) and ASCII (PEM) certificates are both supported.
