2089906 - [macOS] Replace the policies.json-in-the-app-bundle instructions in the admin docs with configuration profiles

Status: ASSIGNED

(Firefox :: Enterprise Policies, task)

Description

[Stephen A Pohl [:spohl]]

The "Configuring policies" guide in the Firefox admin documentation tells admins to put policies.json into Firefox.app/Contents/Resources/distribution. Adding files to the app bundle breaks its code signature (codesign --verify --deep --strict fails), and we want to keep installed bundles intact so that the privileged updater can verify them.

The guide should drop that location and explain how to deploy policies on macOS with a configuration profile for the org.mozilla.firefox domain instead: EnterprisePoliciesEnabled, device scope versus user scope and DisableMacOSUserPolicies, and /Library/Preferences/org.mozilla.firefox.plist for Macs without device management.
