I don't know if it is kindle related but within the last month, there was discussion of an addon for Firefox which allows its user to grab or hijack an account once the user logs on to it. In other words, after you enter your password and are authenticated, the user of this software is ON YOUR ACCOUNT and can do things with it. I don't recall much more but it was yet another scary article about the insecurities of the web and wifi.
Ah, found a link to some site where it is mentioned:
