Have you ever wanted to access a web site using a secondary device like a phone or laptop but cannot remember the password, even though its stored in your FireFox profile on your desktop. Normally you would need to go back to the desktop and access a list saved sites in your Firefox preferences. After finding the site you wish to access, you would get FireFox to uncover the password.
A quicker way of doing this is to just manipulate the DOM using FireBug. By changing the input type from password to text the hidden password is displayed. Simply open FireBug (F12) and use the selector tool to highlight the password input field. Now in the HTML output, change the fields type attribute from “password” to “text”. Once changed, hit enter and the hidden password will be displayed.
Try it using the input field below and discover what the hidden password is?
Of course you can change any HTML that FireBug has captured.
