The problem with blocking trackers and so forth is that it normally causes slowdowns.

This is visible if you use for example Ublock (any privacy filter or any multipurpose filter) you will encounter slowdowns on sites such as groupon and have no ideal why?

It's because they function like black and white and though this is good for you privacy, it's a nightmare for performance. The reason is some sites refuse to finish loading content until they have planted theirs seeds or cookies. What ghostery does is nagivate this landscape for you and decide which seeds are good and which are toxic, dispose of the bad ones, keep the good ones so the site can load without "Access Denied" lag that you get for privacy filters which literally keep the site from loading sometimes for upwards of 10 seconds.

Any user serious about browser performance should disable any privacy list and multipurpose list in their adblock addon and use Ghostery instead.

Ghostery works well and reliably.
Just click on the setup and the five times further to skip the registration is annoying!
Die Bedienung ist recht einfach und das Erlauben von Trackern geht schnell.

it protects is lightweight and very configurable.

great

this is a very good add on

This really is a must have when installing firefox (even more with others i guess...).

Had this version since beginning. Best app ever used besides....

I don't want to block all cookies, and this addon lets me choose which sites to do it on. 5 stars!

I can block specific sites, cookies, and change the defaults whenever I need something different.

Nice for clean searching without all of the ads floating around.
