SecureMac has released PrivacyScan 1.6, an update of the Mac privacy software. The upgrade adds improved compatibility with future versions of Mac OS X (such as Yosemite) and also adds additional Firefox web browser support and fixes.

PrivacyScan will notify Google Chrome, Chromium and Firefox users when their browser is configured to sync with Google’s servers, which can restore erased data. PrivacyScan will also add the capability to clean open windows in many popular apps.

PrivacyScan acts like a digital private eye, identifying hidden threats that can compromise privacy when accessed by advertisers or snoopers trying to see user activity. Version 1.6 is engineered for Mac OS X 10.6.6 or higher.

It costs US$14.99 and is available at http://www.privacyscan.securemac.com. A 15-day demo version is also available.
