+### 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.
