Password Manager?

[Magnumutz]

Well, i think your referring to Firefox's feature that remembers any username and password you want, on which websites you want.

It's basically a menu where you can see all your passwords stored.
So, if you forget a password on a website that you have saved, you can look in the password manager and see the password.

Yes, this sounds risky, right? Yes, if you don't have a master password.

What's a "Master password"?
This is a password that locks the password manager. It will ask you for the "Master password" every time you want to see the other passwords.
