Save Your Passwords Using Sxipper
Sxipper is a free Firefox (1.5 / 2.0) extension which saves your time by keeping track of all of your login details and other personal data. Sxipper encrypts your data and stores in your computer within your Firefox profile, so you shouldn’t worry much about privacy. Its semantic mapping tool learns from its previous mistakes and keeps improves.
Sxipper is a bit bulky, weight around 2.1 MB. After the install, it lets you choose color and icon for your profile. You can import your v-card or manually fill all your details.
Since it automatically logs you into websites, it can prevent you from leaking your passwords in phising sites. When I first read about Sxipper, it sounded like Roboform (which is partially free). I had been using Roboform since ages, but this one really made me convert.
