I'd love it if there was a text document kept up to date somewhere here for importing into this program, with a few nice fast proxies.
Personally, too, for a nice dose of paranoia, I've got the program configured to switch proxies every 60 seconds. I've got a copy of Portable Firefox, and with it came a "secure profile"
http://portablefirefox.mozdev.org/ so, I've now got a full copy of firefox on a USB drive using a profile designed to ensure maximum security. Which is nice.
