Question

Is FastSearch safe?

Accepted Answer

FastSearch is medium risk. Fast Search sets Chrome's default search provider to services.manualsearch-svc.org. When a browser search is routed through that provider, the extension's install code creates a redirect rule that adds action=ds and a persistent GUID from Chrome sync storage, letting the service associate search requests with the same browser profile over time. When you install Fast Search, the extension contacts ext.manualsearch-svc.org and sends installation metadata. The request lets the server observe your IP address, and the response assigns a persistent GUID that is stored in browser sync settings.
