How private is the Opera Turbo feature of Opera?

If I'm using Opera with the Opera Turbo feature turned on (always, not set to "automaticly"). Can anyone see what sites I'm visiting (except Opera of course ...)? Opera Turbo uses a proxy server, so it should be that way, but as a not very technical person I'm not sure.

Why do I want this? Well: nowadays, at least in my country, more and more (legal) open Wi-Fi connections are available. In those environments I like to have more privacy protections. I don't mind if they can see my IP address, but I just want to hide as much as I can of what I am doing.

BTW: I don't care that they can see the data transferred; it doesn't have to be that secret. I only want to hide the requested Internet site links.

BTW: I know that Opera Turbo only works with non-secure websites (HTTP), but that's fine for me. I only want it to work with these sites.

BTW: I'm not need this for illegal purposes; I only want this for privacy reasons.

Solution 1:

You have pretty much answered your own question. True they cannot listen to IP address you are communicating to but they can listen to websites you are seeing as for unencrypted connections it is sent in the HTTP headers (or some compressed headers if Opera Turbo uses that). So your assumption that they won't know what website you are dealing with is quite naive.

To achieve the kind of privacy you want, you can use Tor or set up your own SSL tunnels.
