Ghostery may have an ugly problem with Firefox: missing a few tracker, although add-on has always loaded the latest Tracker list.
There must have been a script, which manipulates the list when FF starts.
About support: has helped. However, had to reinstall all add-ons and re-configure everything.

ADVANTAGES: Blocks the surveillance of a user from different sites in the Internet.
DISADVANTAGES: Sometimes prevents users from switching to another site.

Been using for several years with no problems. Did a great job but not with Firefox 50 update, blocking stats do not show and clicking on the icon only produces a blank page. Tried reinstalling and updating...no luck

Hace lo mismo o quizas mejor, Aun no se!!! pero que las paguinas no lo notan tanto como AdBlock para obligarte a desactivarlo!
es lo bueno que tiene!!!!
Gracias

Ghoster v7 stops working with Firefox 49.0.2 indicating null attacks in every site. To fix the problem I removed the add-on, restarted Firefox, installed Ghoster again and restarted Firefox. So, now it seems to work fine again.
P.S. I use NoScript and Adblock Plus additionally.

It has opened my eyes.

After last update I can do nothing with add-on. Congratulation about update overlays add-on menu and there is no way to hide it!
