Show me the passsword! от Alejandro Brizuela

This addon shows you your password in two ways:

• With a button: shows the password you wrote only when you click the button (Added the preference to leave the password shown on click.
• Always: shows you the password you wrote always (even while you are typing).
• When the password gets focus: shows you the password when the password gets the focus.

Note: This addon doesn't store or use your password in any way, it only shows you what you wrote in the password field.

Disclaimer: In some sites the button could be seen not aligned or not working at all. This could be because that site doesn't respect the web standars.
