BrowserBlur is a tweak released last evening in Cydia, and its role is to hide browser previews in the iOS 7 task switcher. As you already know very well, the task switcher implemented for iOS 7 displays a preview of the last screen opened in an application before closing, practically eliminating our privacy. BrowserBlur is here to help us, it applies a blur effect over any preview of a browser open in the background in iOS 7.
BrowserBlur is available for free in Cydia's BigBoss repo.
