How to Protect Yourself from cookie stealing

*.On Facebook, go to yourAccount Settings and check under Security.

Make sure Secure Browsing is enabled. Firesheep can't sniff out cookies over encrypted connections like HTTPS, so try to steer away from HTTP.

*.Full time SSL. Use Firefox add-ons such as HTTPS- Everywhereor Force-TLS.

*.Log off a website when you're done. Firesheep can't stay logged in to your account if you log off.

*.Use only trustworthy Wi-Fi networks. A hacker can be sitting across from you at Starbucks and looking through your email without you knowing it.

*.Use a VPN. These protect against any sidejacking from the same WiFi network, no matter what website you're on as all your network traffic will be encrypted all the way to your VPN provider.
