// internal state for the extension system in general, not associated

// installation time, whether the extension is enabled, etc.

// browser preferences that an extension controls. For example, an
// extension could use the proxy API to specify the browser's proxy
// preference. Extension-controlled preferences are stored in
// PrefValueStore::extension_prefs(), which this class populates and
// maintains as the underlying extensions change.
