I do this since forever, but I have to give explicit permission to load and run JS, which solves a lot of other problems as well. Letting any site just willy-nilly load code from whereever and run it on your machine is insane, and it's well worth the effort to manually whitelist every site.

uMatrix was and unfortunately still is the best interface for fine-grained opt-in permissions.
