FFsniFF is a simple Firefox extension, which transforms your browser into a html form sniffer. Every time the user clicks on a 'Submit' button, FFsniFF will try to find a non-blank password field in the form. If it's found, the entire form (including the URL) is sent to the specified e-mail address. It also has the ability to hide itself in the 'Extensions manager'. This extension is meant to be as an example of the 'evil side of Firefox extensions'.
