I recommend uMatrix. At first it will take a few minutes to understand how it works, though. You can turn on and off images, css, scripts, XHR, etc, for individual sites or globally. I use it in that manner, with scripting off by default. If I am visiting a new site that needs javascript, I gradually whitelist specific bits until it works and then "save" those settings for that domain.
