Abstract type



(boolean or undefined)

Whether to synchronize the in-memory state of multiple tabs. Setting this to true in all open tabs enables shared access to local persistence, shared execution of queries and latency-compensated local document updates across all connected instances.

To enable this mode, experimentalTabSynchronization:true needs to be set globally in all active tabs. If omitted or set to false, enablePersistence() will fail in all but the first tab.

NOTE: This mode is not yet recommended for production use.
