Network World : How to protect against Firesheep attacks

"Security experts today suggested ways Firefox users can protect themselves against Firesheep, the new browser add-on that lets amateurs hijack users' access to Facebook, Twitter and other popular services.

Firesheep adds a sidebar to Mozilla's Firefox browser that shows when anyone on an open network -- such as a coffee shop's Wi-Fi network -- visits an insecure site.
A simple double-click gives a hacker instant access to logged-on sites ranging from Twitter and Facebook to bit.ly and Flickr." ~Gregg Keizer
