LOS ANGELES (LALATE) – Firesheep, a Firefox extension available in download, has prompted WiFi concerns fro Facebook and Twitter users. Firesheep when used in a WiFi environment reveals Facebook and Twitter have a privacy loophole.

A user wanting to accessing Facebook and Twitter in a WiFi environment might want to think twice today on news that, if another user in the WiFi environment goes online with Firesheep, they will be able to access your Facebook and Twitter account instantly.

Facebook and Twitter have not commented on the news.

Firesheep’s developer Eric Butler said Firesheep was created to show users how Facebook is allegedly not protecting their privacy. The privacy problem, according to Butler, comes as cookies are returned from Facebook. “Web sites have a responsibility to protect the people who depend on their services,” Butler said in a statement to news posted online. “They’ve been ignoring this responsibility for too long, and it’s time for everyone to demand a more secure Web.”

Other websites are vulnerable to the breach as well. Butler adds “My hope is that Firesheep will help the users win.”
