Seriously, I'm been using it for more than 5 years and I've only enabled it for local sites and everything is working.

It depends on what sites you browse. I don't do any social, use google or any other crap, so it's enabled to 0 internet sites with no problem.

If I need to activate it I have a shortkey (vimperator) that opens a new firefox profile (private and prepared to load crap) for the current site so I don't load any terrible UX in my default profile.

NoScript, ublock and SDC are a must for the current state of Internet. It's like drop the garbage out the window than in the garbage bin, you need to put care into it. :)

If I'd use something that required configuration, I think I'd use https://github.com/gorhill/uMatrix. I did use it for quite awhile, but ended up ditching it. Now I'm on uBlock Origin, HTTPS Everywhere and Self-Destructing Cookies. Although I might lose some control, it just works.
