UMatrix has a better interface. The problem is the same, one has to find the minimum set of scripts that does not break the core functionality of the site. It's an ability that can be trained but it's the reason for I don't install it on the browsers of my friends. However I considered installing it, keeping it disabled and using it as a tool to show how much stuff each site loads from so many different sources. Many domain names are very telling even for the uninitiated.
