Firefox

How can I create a Firefox-Profile on my Home Drive (z:)?

The script c:\Programme\Firefox\CreateProfile.cmd creates a profile on z:\Firefox when executed. After that, the old profile can be exchanged by the new one.
(enter %appdata% in the Windows Explorer and then change into the directory \Mozilla\Firefox, the file profiles.ini must remain there, the folder "Profiles\default.???" contains the old profile)
