Form Fox is another security add-on for the Firefox web browser. It deals with web forms as the name suggests and displays the destination url of the submit button in an overlay. Attackers use web forms to submit the data to one of their servers instead of the original server. The problem is that inexperienced users have a hard time checking the destination of the web form on a website as it is visible in the source code of the website.

Even experienced users might not want to check the destination every time they visit the website as this turns out to be quite time consuming when done on every visit.

Form Fox displays the destination directly in an overlay when the user hovers the mouse cursor over the submit form which automates the manual method of looking up a web forms destination url.

A rule of thumb is that a web form is usually safe if it links to a page on the same domain whereas links to other domains should be analyzed carefully before submitting the form data. FormFox is available for all Firefox 2 and 3 editions.
