I'm no friend of advertisers, so I figured it would be good to give solid recommendations about ad blocking software people can use to subvert that exploitative industry, and maybe make yourself just a little bit less surveilled online. Make no mistake, the NSA may be the big bad in the news lately, but what they know about you pales in comparison to data brokers, analytics, advertising, and adtech companies.
If you're using chrome, I highly recommend µBlock Origin. It's better than AdBlockPlus.
Like Chrome, Firefox has µBlock Origin.
Like Chrome, use µBlock Origin.
Use µBlock Origin.
Firefox for Android
Firefox for Android supports addons, which means you can install µBlock Origin!
Safari for iOS
As of iOS 9, content blockers are a Thing. Mozilla makes one named Focus by Firefox.
Hope this helps.
