There are multiple reasons not to use ghostery, besides the fact it is
non-free, they too began tracking users.
I blogged about this a few years back...

Here's some extensions which make your computer much more powerful than just
using Ghostery by far -
* NoScript
* RequestPolicy
* Adblock Edge
* Cookie Controller
* HTTPSEverywhere
Cookie Controller is basically cookie buttons for your browser, they allow
you to do things like disable DOM (evercookies) and block all cookies so you
can allow session cookies on per-site basis.
Other addons to consider, even though they break a few sites:
* LibreJS
* FireGloves or MaskingAgent
* CleanLinks or gprivacy
* RefControl
* HTTPSFinder
* OverbiteFF (not for the normal WWW, but gopher protocol doesn't have
cookies and is spam free) :D
And lastly don't forget the obvious. Networks track you too.
* OpenNIC DNS - (where my blog domain is now) gives a lot more freedom. Try
it out! http://useopennic.org/
* TOR or FoxyProxy for casual browsing, you can't actually post anything
since it gets you blocked on most sites. :P
