something to keep in mind for the future.
if you buy a laptop in the future get one with biometrics (finger print reader) the software for them have password banks. most sites that have a user name and pass login in can be stored in the password bank. when you visit the site all you have to do to log in is swipe a finger.
thus you can set FF so never remember any passwords and not worry about it. they are all locked in a password bank that is locked with your fingerprint.
you could add a finger print reader to any PC as an external device but this is rather expensive just for the purpose of web login.
it's a really nice feature, since I got my new laptop a few weeks ago I don't use the desktop for browsing anymore as most of my sites logins are registered with my fingerprint.
