which would be set in the plist file like this:
```
- <key>Homepage</key>
- <dict>
- <key>URL</key>
- <string>http://example.com</string>
- </dict>
+ <key>Homepage</key>
+ <dict>
+ <key>URL</key>
+ <string>http://example.com</string>
+ </dict>
```
-can be set via the command line like this:
-```
-defaults write org.mozilla.firefox Homepage__URL -string "http://example.com"
+As correctly writing nested values with the `defaults` command can be hard, Firefox also supports writing nested values by separating them with `__`, like this:
+```bash
+sudo defaults write /Library/Preferences/org.mozilla.firefox Homepage__URL -string "http://example.com"
```
Before any command line policies will work, you need to enable policies like this:
-```
-defaults write org.mozilla.firefox EnterprisePoliciesEnabled -bool TRUE
+```bash
+sudo defaults write /Library/Preferences/org.mozilla.firefox EnterprisePoliciesEnabled -bool TRUE
```
