Mozilla Thunderbird Portable is the Mozilla Thunderbird email client packaged as a portable app, so you can take your email, address book and account settings with you. Portable Thunderbird is the safe, fast email client that's easy to use. It has all the same great features as regular Thunderbird including quick message search, customizable views, support for IMAP/POP, or RSS support. Plus, it leaves no personal information behind on the machine you run it on, so you can take your email and address book with you on your iPod, flash drive or other portable storage device.
