Sounds pretty great, doesn't it, and for now, it is free.  But, I see shadows from much earlier in our Web time frame.

In 1999, I was a downtown DC city fair.  We were all having a lot of fun and I ran across a booth with a company named Zero-Intelligence.  If you signed up, you could surf in total anonymity.  Truly, there was no way to track you, as your browser's request was stripped of most information, then went through three proxy server and back came the page, no cookies, nothing.

They had an email component.  Most people seemed to get three of these addresses.  The idea was to use them for shopping, personal, and whatever else.  The company, with the way it was set up, had no way to track who sent an email - sort of.  Most people paid by credit card, that is always a strong trail, but, in this case, it could stop them before they go going, or they might get lucky.

The big issue for this really nice company was that it was 1999.  Most of us had some form of dial-up, I had ISDN, I believe, and the service was just too slow to survive.  They added an anti-virus program, then a firewall, but, they could not get the main product into the hands of enough people.  Eventually, they turned to big business and set up major security protocols for their clients.  Here is a bit on Zero-Knowledge, from 1999,

Privacy was such a big deal then, as it is now.  And, though it is still important, one only has to look at the number of Social Media sites of any kind and there are millions of people around the world sharing more than they may realize.

To me, it is just funny to see it come around to now giving us a anonymous browser: Ixquck which is a Firefox add-on,

or one can go to www.Ixquck.com
