How do you back up settings and everything??
Here I copy and paste C:\Documents and Settings\"USERNAME\Application Data\Mozilla folder to another partition/usb as backup.
If you delete that folder or move it to another location and on restarting Firefox it will go through the motions of a fresh install.
Inside of the Mozilla folder there is a Profile folder.
If trying out FF portable you can delete the contents of the profile folder within then copy and paste the contents of the Mozilla Profile folder which will give FF portable all of your settings.
There are tools such as MozBackup that some people use for backup purposes.
