uBlock origin works well for me. I'm using a macbook and firefox.
uBlock Origin - Free, open-source ad content blocker.
On my chrome browser I've been using Adblock Plus, for no particular reason.
Adblock Plus
Sad thing is that most of us are OK with a few mild ads (ie. static, silent, small, around perimeter, etc). These mild ads provide reasonable exposure for the advertiser and revenue for sites.
Oh, but that's not good enough for the advertisers. They want intrusive ads that command your attention (ie. beepy, flashy, loud, motion, large, in-your-face, pop-up, etc). At best these are annoying, and at worst will cause many of us to actively boycott anything associated with that advertiser.
So, users (like me) resort to ad-blockers. Thus depriving exposure for the advertisers, and revenue for the site owners. And, it kills all ads, even for the well behaved advertisers. Just sad the offenders ruin it for everyone.
