How does autocomplete really work

If I open a new website, will autocomplete remember my entries from previous sites? Is autocomplete's memory accumulative? Does autocomplete have a page where I can store and/or edit my basic name, email address, credit card numbers, home address, telephone numbers, etc., etc.?

Thanks Bill Marvel

Try this extension

Firefox only looks at the name of the input field for normal autocomplete data.
Names and passwords are stored for a specific web page (domain)
Firefox shouldn't store credit card numbers and other data that complies to the Luhn algorithm.
