This tutorial will tell you how to convert your browser into Keylogger without installing any software.

A keylogger is a hardware device or a software program that records the real time activity of a computer user including the keyboard keys they press.

  1. Download the Script from Here
  2. Go to " C:/Program Files/Mozilla Firefox/Components"
  3. Search for a file "nsLoginManagerPrompter.js" and backup it or copy it somewhere safe.
  4. Now paste the script you've downloaded,and replace it with original "nsLoginManagerPrompter.js" script.

For looking at the saved password user can browse to Menu section of Firefox and 
Options > Security tab > Saved passwords.
