OperaTor is a combination of Opera, the anonymization service Tor and Privoxy similar to Foxtor which offers the same functionality for Firefox. I don’t want to bore you with a lengthy technical description of how Tor is providing anonymity, just that much: Tor uses a layered approach sending your request through a series of servers that only know the server before and after them. This means that the destination server does not know that you requested the package, it only knows the IP of the server before that made the request.
