Omg how stupid some people are... Today at my university I used the first time one of the computers in the computer room and there is a portable Firefox installed in a shared space on the computer and that is also where it saved settings etc. So this is the same for every user on that particular computer.

And when I checked the security settings I found that about 10 different accounts were saved and accessible with website username and password.

So of course the shared space Firefox is bad, but you still shouldn't save you password on a public computer :S

PS: If anyone needs a webmail account or an account for the german university network contact me :P
