User:P.A./Form user experience improvements

Overview

Submitting information to visited websites, using a web form or similar mechanism, is an increasingly common use case on the Internet.

Web forms are currently the preferred way for websites to ask the user for different types of information:

• Common personal information, for example a name and address for shipping a product.
• Other identifying information that may be specific to one website, for example a username.
• Authentication of identity using a secret key, for example a password.
• Authentication and authorization of payments using secret credit card data.
• Recurring input that may be specific to one website, for example search terms.
• Information that may be reused on different websites, for example the e-mail address of a contact.
• Miscellaneous information that is entered only once, for example a message.

Each type of information has different characteristics, but most of them can generally benefit from a mechanism that is able to remember past input and help the user in entering the same data again, on either the same website or a different one.
