If you want to rid your Web browsing experience of ads, your best bet is AdBlock. If you want to replace the ads on some sites with equally or arguably more distracting feeds from Facebook, Instagram, or Twitter, however, then there is the Post Forward extension for Chrome.
After you install the Post Forward, you can then head to the extension's site or click the button the extension installs to the right of Chrome's URL bar to connect to any of three aforementioned social networks. The extension will then replace ads on some sites -- a select few in my experience -- with a scrollable window of one of your social network feeds of its choosing.
Using the panel that is accessed from the extension's button, you can pause Post Forward should you find it blocked a pop-up window that it thought was an ad or creates a browsing experience more distracting than one littered with ads.
