Hacktivismo, a group of human-rights advocates and computer security experts, has released Torpark, a Firefox-based browser designed to allow anonymous Web surfing. The browser is based on a modified version of Portable Firefox.
The browser can be run directly from a USB drive, meaning it can be used on public computers. It creates an encrypted connection to the TOR (The Onion Router) network, which supplies a succession of different IP addresses.
"Torpark causes the IP address seen by the Web site to change every few minutes, to frustrate eavesdropping and mask the requesting source," Hacktivismo said in a statement.
