Rated 2 out of 5 stars
After updating today, 25 July 2013, all my buttons were gone and the Search Bar reinstated.
In addition, after choosing to use Manual Blocking, the Addons page loaded in Spanish.
So I guess I'm going to uninstall the latest version and go back to using the previous one since I don't want the Ad blocking feature. I've got Adblock Plus for that.
