So I am listening to Security Now podcast and they talked about the fact that Firefox stores your passwords in the clear inside the browser and anyone that walks up to your computer can view them.
All they have to do on a mac (windows is the same) is: Preferences-> Security -> Show Passwords -> Show Passwords
BAM!!! There are all your passwords. You can check “Use a Master Password” to protect yourself.
Now on to Internet Explorer, it appears there is no way to protect the passwords and simple tools like: IE Passview make it simple for anyone to display your passwords.
I don’t know if Safari or Opera has this same problem, but it just goes to show you don’t store anything in your browser…
