Firefox keeps using the same walker after navigation and expects it to publish the new document root. Normal tab debugging also relies on target switching. Re-inspect the tab when navigation finishes, replace the walker DOM data, and notify the watcher that the previous top-level frame target was destroyed before a fresh target becomes available. Send target availability as a watcher event, not as the watchTargets response, and give each navigation a new inner window id so Firefox can associate the new target with the new document.
