So far this extension has been working very good. I have not noticed any changes in the speed of pages loading. Very informative as well. I am liking this extension more and more!!!

yes

This add-on is amazing. It protects me from so many trackers, and I love how you can click on it and see how many trackers websites are trying to get by

Very good Add on. Blocks ads and it's "pause" function works really well for sites that sometimes can't work when the addon is enabled (like Yahoo! mail's search function i.e).
I used to have an adblocker, cookie deleter and a scriptblocker and both have been replaced by Ghostery.

I love it

I can see the appearance of ghosts clearly.

Lightweight and basically invisible, when left to its own devices Ghostery will pop up and inform you of just how many trackers/ads/scripts it is blocking, and then retreat quietly back to your toolbar. Customizing your settings is a breeze, and for the occasional time when you want to suspend it, whitelist a site, or whitelist just a particular web plug (on its most severe settings, which I use, it will block Soundcloud embeds, which I wanted to whitelist, for example), a few clicks around in the toolbar menu will have you back whatever you were doing on the internet.

For me it has been a fire-and-forget operation; between Firefox's generally impressive prioritization of security and Ghostery, I have mostly wiped out the internet security concerns that were bothering me. Good stuff.

Ghostery is very user friendly and blocks all of the adds and trackers that i have come across. If is is blocking something that is braking the page then can stop it.

Better than the better adblocker.
