uMatrix or uBlock (in advanced mode) can largely accomplish the same in a simpler way. However, in my experience, if you go the 'default deny' route against scripts, the spread is about 33/33/33, with 33% of the pages working perfectly, 33% breaking in small ways, and 33% completely borking up. Yes, you can then add the necessary scripts to a whitelist, but it gets tiresome to constantly have to 'fix' sites.
