It looks like it's been renamed to 'tails'.
It is based on Debian, is a LiveCD and it's purpose is to preserve anonymity and privacy.
When you install it in a VM it gives a pop-up to this link saying that running it in a VM may not be the safest option.
There's a few default plugins in iceweasel (looks like firefox, in fact it is a fork of firefox):
- adblock plus
- amnesia branding
- cookie monster
- foxyproxy standard
It also starts with TOR configured and in 'private browsing' mode. There is also an I2P application/network that can be used. Both are however quite slow (but generally this shared type of proxy-ing usually is?) As in ~10 seconds to load a web page.
Easy to use, but still slow.
Is performance is something worth losing to gain privacy and anonymity?
