The JonDo client includes an option for accessing the Tor network. Given some of the features (excerpted below) it seems to use a custom Tor client. Are there known vulnerabilities?
JonDo has Tor support, but it is experimental. This is why we do not guarantee complete or flawless functionality. If you would like to use JonDo to access the Tor network, you will need to enter JonDo as a SOCKS (not as a HTTP/HTTPS) proxy in your browser.
