-// The PasswordForm struct encapsulates information about a login form,
-// which can be an HTML form or a dialog with username/password text fields.
-//
-// The Web Data database stores saved username/passwords and associated form
-// metdata using a PasswordForm struct, typically one that was created from
-// a parsed HTMLFormElement or LoginDialog, but the saved entries could have
-// also been created by imported data from another browser.
-//
-// The PasswordManager implements a fuzzy-matching algorithm to compare saved
-// PasswordForm entries against PasswordForms that were created from a parsed
-// HTML or dialog form. As one might expect, the more data contained in one
-// of the saved PasswordForms, the better the job the PasswordManager can do
-// in matching it against the actual form it was saved on, and autofill
-// accurately. But it is not always possible, especially when importing from
-// other browsers with different data models, to copy over all the information
-// about a particular "saved password entry" to our PasswordForm
-// representation.
-//
-// The field descriptions in the struct specification below are intended to
-// describe which fields are not strictly required when adding a saved password
-// entry to the database and how they can affect the matching process.
