Download OperaTor 3.5

OperaTor weights 10 MB and is Windows only. After the download is finished:

  • check its MD5 checksum: 7a288e64811219b0ccc081398632288f *
  • extract the archive to the location of your choice
  • launch the OperaTor.exe file to start all the necessary applications

Please do not link directly to the files. Link to this page instead.


The only protocols which OperaTor anonymizes are HTTP and HTTPS, thus if you want to stay anonymous you should avoid using other Opera features (e.g. Java, JavaScript, Bittorrent, integrated e-mail and IRC clients).

OperaTor comes with absolutely no warranty. It is the user's responsibility to test whether the connection is secure. Users should keep in mind that OperaTor relies on Tor (The Onion Router) and Polipo and any security questions should be directed to their developers.

Thank you for a great

Thank you for a great program!

I've been trying to use Tor, Privoxy and Opera separately but I always had problems running them, frequent crashes, configuration problems, etc. OperaTor runs great each and every time.

Which brings me to my general question: After starting Operator I often go to various IP finder sites and browser security sites and they all show the Tor exit node instead of my real IP, as expected. I've turned off all Java, plug-ins, Javascript, cookies and referrers from the bottom button bar.

Which of these functions will allow a website to see the real IP even though OperaTor is used? I know Java can show the real IP, but is it possible to get the IP by allowing Javascript too? How about cookies? If I allow cookies and sign in a web forum for example, can the website get a real IP only by using cookies and maybe cookies and Javascript together? I don't thing IP info is included in referrers.

Thank you very much for your efforts and your generous offer.

Your question about JavaScript and plug-ins is answered in the Tor wiki: So I'm totally anonymous if I use Tor?

Here is an excerpt:

Java, Javascript, Macromedia Flash and Shockwave, QuickTime, RealAudio, ActiveX controls, and VBScript are all known to be able to access local information about your operating system and local network. These technologies will work over proxies and can tunnel the information back to their source.

Javascript only

I read somewhere that it's Firefox that contains extra Javascript stuff that can reveal your true IP address with only Javascript enabled and all other plugins turned off. But I can't find any website that can actually prove this and reveal my true IP using Javascript only. Does anyone know of a site that proves that Javascript on its own can leak true IP info via Opera/Tor?

A lot of websites, blogs and forums nowadays require that you have Javascript turned on.

Even the captcha system used here seems to require cookies be turned on, but thankfully doesn't require Javascript.

The Javascript to reveal

The Javascript to reveal your IP address uses the class which is disabled in Opera.

Nonetheless, more and more developers are using Flash as a payload for multimedia content. Actionscript allows you to create direct sockets using the class, but it seems as if Opera passes sockets through the proxy by default (correct me if I'm wrong). I looked it up, and it seems like Flash 10 can only reveal your IP through malicious code. Myspace or Youtube is not going to get your real IP.

In addition, Opera makes DNS requests through the OS if it doesn't get a timely response through Tor.

Delete cookies

That's true. The CAPTCHA installed here requires your browser to accept cookies but you can always enable the Delete new cookies when exiting Opera option in the site or global Opera preferences.
