xB Browser (formerly known as TorPark

Tor and XeroBank anonymity networks, and is available as component of the xB Machine[6]
and the xB Installer.

It is designed for use on

encrypted connection to any of the Tor or XeroBank routers can be created from any computer with a suitable Internet connection,[8] and the browser clears all data that was created on the portable drive upon exit or on demand.[7]

In March 2007 it was reported that the xB Browser was downloaded 4 million times[7] and in February 2008 over 6.5 million downloads making xB Browser the most popular anonymous browser on the Internet.[9]


Steve Topletz co-released Torpark v. with

Portable Firefox web browser with built in support for Tor[1][4] and using the Nullsoft Scriptable Install System.[citation needed] In 2007 it was redesigned from scratch.[citation needed

A cross-compatible version for

Mac OS X and Linux was being developed based on xB Machine, due to be available in August 2008,[12]
but the development seems now abandoned.

Network usage

Tor network

xB Browser routes

9050. This port can be changed via xB Config, an INI generator for xB Browser.

XeroBank network

xB Browser is optimized for use on the XeroBank anonymity network, which is a private and commercial broadband network operated by Xero Networks AG.[12] The XeroBank network routes traffic through at least two multi-jurisdictional hops.[citation needed] In contrast to Tor, the XeroBank network supports both TCP and UDP protocols, performs channel multiplexing for low observability, is run by a single entity and costs money to use. The XeroBank network is accessible via SSH and OpenVPN protocols. xB Browser internally manages a SSH connection to XeroBank, but will recognize and submit to OpenVPN connections.


Besides the anonymous networks, xB Browser uses following add-ons:
