im using IRON 21.0.1200.0 version in windows8 x64 pro.

it's have a test in http://www.pcflank.com/details.html,

-------------------
Browser privacy check

The test checked if your web browser reveals any private information while you visit Web sites. Usually such information is: the last site visited, your locale and who your Internet Service Provider is.


Attention! Your browser is not private. Privacy is 50%
While visiting web sites your browser sends information about previous sites you have visited.

Recommendation:
Install a personal firewall program. If you already have a firewall, adjust it to block this information.
---------------------

um...

Those tests require you not to be connected to the internet at all to pass them.
So, it is more conflicting to rely on it, but the test does have a point, we are not secure while online regardless of browser.
