The passwords are already encrypted in a text file in your profile folder.
To keep it, just save it in another folder.
If you want to reinject it in a new profile, it's really easy.
1) Copy it in the new folder (file has .s extension)
2) copy from old prefs.js the line concerning this file, and paste it in the new prefs.js. (delete before a similar line if already present in the new prefs.js)
3) Launch the new profile.
That's all folks...
