To deploy Firefox Enterprise Policies via the policies.json file across Windows, macOS and Linux, follow these steps:

First use your Policy Creation Toolkit to build your Enterprise Policy.

Windows

• Save the file:

     C:\Program Files\Mozilla Firefox\distribution

• Ensure the folder structure matches what you need for your policies.
• Restart Firefox to apply the new policies.

macOS

• Save the file:

     /Applications/Firefox.app/Contents/Resources/distribution

• Restart Firefox or log out and back into your macOS session for changes to take effect.

Linux

• Save the file:

    /etc/firefox/policies/policies.json

• Restart Firefox or log out and back into your Linux session for changes to take effect.

Common Considerations

• Permissions: Ensure that the user has sufficient permissions to modify files in these directories.
• Firefox Version: Check the compatibility of policies with your version of Firefox, as some policies may only be available in newer versions.
• Backup: Always back up existing policy files before making changes.

By following these steps, you can successfully deploy enterprise policies for Firefox across multiple operating systems.
