These are my favourite Google Chrome extensions at the moment.

 

Ghostery

Basically what Ghostery does is it detects trackers, web bugs, pixels, and beacons placed on web pages by Facebook, Google Analytics, and over 500 other ad networks and blocks them.

 

ScriptNo

ScriptNo is very much like the famous NoScript for Firefox. In my opinion, it is the best plugin of that kind for Google Chrome.

 

AdBlock

The best way to block ads.

 

Youtube Options

If you often watch Youtube videos, you should get this extension.

 

Better Pop Up Blocker

This will block all the annoying pop up windows.
