password recovery

how do i retrieve passwords from websites that my friends visit?im a noob when it comes to things like this.are there anysteps that i need to do or is there software available to do this?

if they use mozilla, and are dumb as hell, go to tools -> options -> security and hit the big "Show Passwords" button.  if they're dumb, CONRAGTULATIONS! you know many of their passwords now.

or just secretly install a keylogger or something.
