I started using Privacy Badger from the Electronic Frontier Foundation several months ago. It is a browser extension — I use it with Chrome — which blocks or restricts domains known to track identities and activity across the web.
One can click on the Privacy Badger extension icon to see what has been blocked, and also to make exceptions for the website being visited if needed.
This includes live links to tweets and other social media, which Twitter uses to gather data about the viewer. I allow these on certain sites which curate related tweets into stories.
I don't actively use Twitter any more but still find the zeitgeist there to be informative.
