Privacy addons like Ghostery block social sharing buttons and trackers. Priv3 protects your privacy by blocking trackers, but still shows social snippets like Facebook Comments, +1, like buttons. Once you interact with the social snippet, it reloads the cookies and tracking starts again. The addon is only available for Firefox, so all I can do is wait for a Chrome version of it to be released. The Priv3 Firefox Extension is available only for Firefox users, so we’ll wait for Chrome version.
