18 // The PasswordForm struct encapsulates information about a login form, | |
19 // which can be an HTML form or a dialog with username/password text fields. | |
20 // | |
21 // The Web Data database stores saved username/passwords and associated form | |
22 // metdata using a PasswordForm struct, typically one that was created from | |
23 // a parsed HTMLFormElement or LoginDialog, but the saved entries could have | |
24 // also been created by imported data from another browser. | |
25 // | |
26 // The PasswordManager implements a fuzzy-matching algorithm to compare saved | |
27 // PasswordForm entries against PasswordForms that were created from a parsed | |
28 // HTML or dialog form. As one might expect, the more data contained in one | |
29 // of the saved PasswordForms, the better the job the PasswordManager can do | |
30 // in matching it against the actual form it was saved on, and autofill | |
31 // accurately. But it is not always possible, especially when importing from | |
32 // other browsers with different data models, to copy over all the information | |
33 // about a particular "saved password entry" to our PasswordForm | |
34 // representation. | |
