You can download a portable version of Firefox and Thunderbird (e-mail) at http://johnhaller.com/jh/mozilla/

I have used both programs from a USB drive and they work well. You *should* be able to copy your existing profile into the portable version (I am not sure if all extensions and themes are compatible). I have an extension for Thunderbird that minimizes it to the system tray that will not work on portable Thunderbird, it needs a particular .dll on {win dir}/system but besides that I have had no problem.

How was your loading speed on a USB device? I would imagine that if you wanted to run a large application from it, you'd need one of the higher speed devices. Also, do you let it write cache to the device? I figure that if you did, you'd see a significant decrease in the device's lifetime, as they can generally only be written to so many times before sectors start failing.
