The features are the same as Search Engine Security for Google Chrome, released two weeks ago. The Referer and the User-Agent headers are modified when you follow a search result link on Google, Bing and Yahoo! This prevents the hijacked sites from redirecting users to a malicious page.
As with SES for Firefox and Google Chrome, you can turn the extension on and off for the three search engines.

The options are available under Tools > Search Engine Security options.

To test the features, search for "what is my user agent" or "what is my referrer" in Google, Bing or Yahoo! and follow a link. You will notice a different value when Search Engine Security is ON or OFF.
