Protect Accounts against Firesheep

Firesheep is an add-on for Firefox that can let anyone scan through open Wi-Fi network and steal account information of users.
Account details of websites like Twitter, Facebook, Yelp, Hotmail and several others can easily accessed using this add-on.

To protect your account details from getting hijacked by anyone. Here are some pointers shared by Butler to protect users in the simplest possible ways:

1) HTTPS-Everywhere Extension: Created by Electronics Frontier Foundation, this add-on makes the Firefox browser use only HTTPS (Secured) connection for certain websites. Unfortunately, this works only with definite list of websites only.

2) Force-TLS: Yet another Firefox extension that will let users to specify and create own list of domain names for forcing HTTPS requests.

3) Virtual Private Network: Using Virtual Private Networks could be an ideal solution for corporate environment and hardly for a home based user.

These aren't the ultimate solutions that will serve the purpose of securing your account details being hijacked over open Wi-Fi.

However, they do promise protection against snooping through Firesheep or similar tools.
