Chrome/Firefox/Safari: Disconnect, one of our favorite privacy protecting browser extensions, has been updated to protect you from session hijacking (sidejacking/widgetjacking) attacks, where an attacker logs in to web services as you because a site you visited happened to use an insecure connection to conact Google, Facebook, or some other service thanks to an embedded widget or social plugin.
The new feature is called Secure Wi-Fi. The video above does a great job at explaining how session hijacking works and how Secure Wi-Fi protects you from it. Although we've discussed you can protect yourself from this type of attack in the past, the Disconnect update does a great job of both protecting your security as well as protect your privacy from advertisers, spammers, and other prying eyes. Secure Wi-Fi in Disconnect currently protects you from hijacked YouTube, Facebook, LinkedIn, Google, Gmail, Twitter, and Yahoo sessions, with more on the way.
The developers behind Disconnect pride themselves on building tools that don't break the web while keeping you safe, so unlike other extensions, you can trust that the sites you visit will still work normally once Disconnect is installed. The add-on is free, and the updated version is available now.
