 <Warning>
-  Multiple tab support is not currently available on Android or Safari.
+  * Multiple tab support is not currently available on Android. 
+  * For Safari, use the [`OPFSCoopSyncVFS`](/client-sdk-references/javascript-web#sqlite-virtual-file-systems) virtual file system to ensure stable multi-tab functionality.
 </Warning>
 
 Using PowerSync between multiple tabs is supported on some web browsers. Multiple tab support relies on shared web workers for database and sync streaming operations. When enabled, shared web workers named `shared-DB-worker-[dbFileName]` and `shared-sync-[dbFileName]` will be created.
