Values

Addons: A Boolean. Controls whether syncing addons should be enabled.
Addresses: A Boolean. Controls whether syncing addresses should be enabled.
Bookmarks: A Boolean. Controls whether syncing bookmarks should be enabled.
Enabled: A Boolean. Controls whether sync itself should be enabled.
History: A Boolean. Controls whether syncing history should be enabled.
OpenTabs: A Boolean. Controls whether syncing open tabs should be enabled.
Passwords: A Boolean. Controls whether syncing passwords should be enabled.
PaymentMethods: A Boolean. Controls whether syncing payment methods should be enabled.
Settings: A Boolean. Controls whether syncing settings should be enabled.
Locked: A Boolean. Controls whether the settings are enforced, and whether Enabled applies at all. If Locked is true, the Sync data type settings are locked so users cannot change them, and Enabled connects or disconnects sync. Users can no longer turn sync on or off themselves, whether Enabled is true or false, and only a policy update can change it.
