freakin fantastic Rated 5 out of 5 stars
a must have for anyone with many must have addons. i'm a huge FF customizer and adore being able to take my configurations with me. also handy for transferring your home configs to your portable FF (runs on a thumbdrive so you dont have to install on someone else's comp)
if you have even one thing that you *have* to have in your firefox, get FEBE and make sure you can always get it!
