firesheep plugin for Firefox

Found this awesome plugin that can be used to test how secure your logins are when used with a non secured (open) wifi link. It basically captures the cookies as it passes by the wifi link. But keep in mind its pretty limited as in when you logout of you session (gmail, facebook, etc) it makes the cookie (if captured by someone) invalid. So making it impossible to login using the captured cookies.

here are some screen caps.
