uMatrix is a must have add-on and nothing else comes close to matching its functionality. It pairs well with uBlock Origin (same dev). Add-ons like Decentraleyes is also good as it prevents persistent tracking from shared web libraries, like Google ajax, that everyone seems to use... it's free and widely available for a reason.

Google is also working to update Chrome APIs that will cripple privacy centric add-ons and those that allow ad-blocking, like uMatrix and uBlock origin soon, so enjoy it all while it lasts.
