Most password keepers just store and fill in passwords and logins for different web pages. People grew accustomed to these nice form fillers, they more thickly use password saver (because they want to keep passwords safe), password storage, password finder and other password tools.
Password Commander (password manager) fully supports all common browsers, including Internet Explorer, Opera, Netscape Navigator, Maxthon, Mozilla, Firefox. It does not just fill in password and login fields - it can automatically fill (autofill) in all required fields for websites and any Windows application. Can you think of a second password manager capable of that? You will love this feature, whether you have only a couple of passwords or couple of hundreds.
