Don't expose your Facebook and Twitter passwords - Use a VPN.

Firesheep, is a new extension for the Firefox browser, that lets users eavesdrop on unencrypted traffic over unsecured wifi networks (most Public WiFi Hotspots), exposing among other things your Facebook and Twitter passwords.

This extension for the Firefox web browser makes it easier than ever for anyone so inclined to steal account information from other users logging on to websites via unsecured wifi networks.The Firesheep extension collects the “cookies” that websites such as Facebook and Twitter use to allow access, and then allows the user to “sidejack” other people's accounts.

Firesheep collects user information and shows it in a Firefox window, it then lets each account be taken over simply by clicking on it.

Cookies from Amazon.com, Basecamp, bit.ly, Cisco, CNET, Dropbox, Enom, Evernote, Facebook, Flickr, Github, Google, HackerNews, Harvest, Windows Live, NY Times, Pivotal Tracker, Slicehost, tumblr, Twitter, WordPress, Yahoo and Yelp are all collected automatically, but other sites can be added if you know a little about programming.

Most websites protect your password by encrypting the initial login, but the majority do not encrypt anything else leaving you open to exploits like Firesheep. 

If you want a more secure web, then take a look at our HeroVPN service which would protect you against the Firesheep exploit and much more.
