Backup Firefox, Thunderbird, and Gaim profiles with the click of a button. Then restore them just as easily. Backzilla. Net is perfect for backing up all these profiles. No need to install. Once the profiles are backed up, you can transfer the folder to a new computer and use the restore feature to apply your profile to the new computer. If, for some reason, the restore fails, there is an undo feature. Version 2.1 has Backzilla.
