I'm using it in combination with µMatrix.
I'm curious: how do you use it? Do you have to mass-enable stuff using the 'power' icon, for many sites? Or do you just enable the things you know you need, on a per-site basis? Or are your default just good enough?
The reason I ask is that I was curious about it, so tried it out for a couple of days. I found many sites were not usable with the default settings, e.g. Udemy's login box didn't show up until I turned off µMatrix.
Sites using cloudflare are a major issue here, specifically their cryptic subdomains. If someone were to hide an ad network behind those they would be hard to tell apart from the rest, at least for humans.
