Have you ever noticed this pop up ? When you enter any password with Login ID at your Favorite Social bookmarking sites like Orkut, FaceBook , Myspace Or e-mail sites Like Gmail, Yahoo, Rediff, Or even highly secure sites like Paypal (Paypal never allow Firefox or any other browser to remember passwords)
Actually this pop up is asking you to save your password in Firefox (or other Web browsers) memory so that it will allow direct access to these site , without entering your Login ID and password again and again.
But this practice may be really really , risky in terms of your password protection, anyone who is having access to your PC can easily recover or Hack or retrieve these passwords and and can LogIn with your Information and do changes to your profile or may steal money too. !!
This Simple script can easily recover or retrieve your Passwords from web browsers (Works fine one Firefox and Internet Explorer)
And even If you have some problem with this script you can simply change the preferences from FIREFOX (ONLY) Got to Tools >> Options >> Security >> and the Show passwords
and see all the password stored my your Firefox ..
So It is Highly recommended to all the Internet users NO TO Check the ” REMEMBER PASSWORD ” check boxes or ” click on NEVER ” when firefox asks for password to save.
I also recommend you to Lock your Computers to be safe from such hacking attacks
But this script is only useful when you have direct access to others computer
, and he/she should not nearby at the time of placing the script …. 
It’s good to have information like this ..
Thanx..
