Secure your Firefox passwords

If you're using Firefox as your web browser, do you use its Remember Always feature when logging in to your e-mail, multiply, etc.?

Do you know that passwords that you save in your Firefox browser can easily be seen by people accessing your machine? Yup, the passwords are in plain text for people to see along with your username and the URL that it can access.

If you go to Tools > Options > Security > Show Passwords, you could see something like this:

Go ahead, check it out first

Fortunately, Firefox also allows you to protect this feature with some sort of master password.
In Tools > Options > Security, simply check the Use a master password box. You will be prompted for a password that will be asked once per session when you access a site with a saved login detail.

This is extremely useful if you are using Firefox portable in your flash drive just in case you lost it.
