Ad-Away (installable via F-Droid if you are rooted) allows you to block ads at the hosts-file level, which will work in Chrome and in other apps that display ads.

Before anyone chews me out, as this effectively renders many free apps equivalent to their premium (ad-free) counterparts, I usually pay for said premium versions to compensate their developers.

The catch here is that it isn't as good - using uBlock in FF for Android for example will properly block all ad frames.

Using adaway or a pi-hole for that matter will not - they will only cause ad loading to fail (in some cases) - which sometimes results in frames showing errors on the page instead of a clean rendering of nothing with ad divs removed.

Personally I wind up using several methods - AdAway to kill most app ads, uBlock for web and Xposed to kill YouTube ads since the hosts-based methods seem to work rather poorly for them as their subdomains change all the time.

DNS-level blocking is, IMO, only a second line of defense. Nice to have for all those devices and applications where you cannot have a proper ad/tracking/malware blocker.

That's weird, I didn't get any Youtube ads in quite a long time, and only use AdAway.
