Fireform is able to fill out most forms automatically when you right-click the icon of the extension in the status bar and select fill in this page – left-clicking the icon has the same effect. You will have to create a profile before you can start using the automatic fill option. The profile is independent from existing Firefox profiles and will be used only for the FireForm extension.

You can supply information like names, contact information (email, phone), address and misc information like birthday. Once the profile is created you can use FireForm or create more profiles for other users that use this computer.

There might be the time when you come upon a website that uses a field that is not covered by the default selection that you edited in your FireForm profile. It would then be time to add a custom field to FireForm by using the Display Fields option of it.

Now hover over the field that you want to add and FireForm should display information about that field, the most important is the name that the developers have chosen for it. Remember that name and go to tools > fireform > advanced profiles management and add a description that you can choose freely, a value that should be automatically entered and the trigger that was displayed when you hovered over the form.

Sites tend to use different names for the same subject and you will have to edit those settings often in the beginning. You can add additional triggers to a form by separating them with “;”.
