This should be great on mobile. On mobile there are no extensions and there are at least two news sites I frequent that abuse it by showing a full page popup before every article.
Have you tried using DNS66 as adblocker?
It's implemented as local-running VPN and doesn't require root. I'm using it since a year or so and quite happy with it.
