To be clear, that tutorial was made in 2007, so is a bit dated. Also, it shows how to set up FF to use the proxy, but the idea of a tunnel is not FF-specific, nor is this vulnerability. One big issue with SSH-tunnel as a solution is that anything not set up to use the proxy still works, it's just quietly vulnerable. Any suggestions on making TCP traffic which doesn't go through the proxy totally fail?
