The Tails live CD is meant for anonymity but might its security features make it a safer way to do your online banking, shopping and bitcoin shopping using its "unsafe browser", compared to a regular debian live CD? Tails is supposed to be fully open source for starters, but can someone confirm this? Might a libre derivative of debian be safer for the stated purposes? Might a Kali live CD be safer? What about the TENS live CD for the US military?
