I had to remove this app from my system because it was preventing me from signing on to Disqus, which I use for the purpose of commenting on different news web sites.

The product does work to block ads, but this was "overkill" for my purposes, lol

Love this addon but the last few releases have been broken for me, when I click the icon its blank and crashes the browser. I had to go back to to version 8.0.3.1 to get it working again. Firefox 58.0.1 Windows 10

This kind of addon is really what I hate. They claim to defend users by blocking trackers but their business model is actually selling your data to that very companies they claim to protect you from.

It's like Adblock plus. They get payed by advertisers to set them on the whitelist, that they of course enable by default because they know the general user will not touch that setting.

Firefox has its own track blocker build in, you can now enable it always on. I additional use ad-nauseam with some tracking filters enabled. It may be counter productive because ad-nauseam actually can click every ad for you in the background to generate false clicks and make them pay more money so they may be able to track you better but I just love that concept.

Replying to the dev below:
1. User data - tracker data. tomatos tomatos.
2. OK how are you making money now? I will not read that article. You are absolutely untrustworthy because you had a parent company like that in the first place. And probably doing some other new shady stuff.

Je suis utilisateur de Ghostery depuis plusieurs années mais la, cette dernière mise à jour ralenti énormement mon firefox. Un des processus de firefox reste entre 20 et 40% d'utilisation CPU. Le navigateur ne répond plus quelques secondes régulièrement. l'utilisation de Bing marche mal, la page est en chargement permanent (la partie où l'on voit si on est connecté à son compte microsoft n'apparait jamais). Plus il y a d'onglet plus Firefox se met à figer pendant plusieurs secondes de façon fréquente et cela dégrade complètement l'utilisation. J' ai tenté de désinstaller et de réinstaller l'extension mais ça n'a rien changé. Symptômes constatés sur 2 pc différents. Tous ces problèmes disparaissent une fois Ghostery désactivé. J'espère un correctif rapidement car jusqu'ici, cette extension est top, si ça reste comme ça, je vais passer à Disconnect ..

The single most annoying plugin I've ever seen. Great they stop trackers, but can they STOP advertising themselves for a single second?
It's impossible, this god damn extension is always poping up to say something about itself or its developers...

Removed.

Весело мигает кнопкам, крутит колесики, бегают циферки полная имитация бурной деятельности. По факту - ноль, дупло., дыра черная.. То-ж rutracker.org хоть и определился как сайт из списка но открыть не осилило. Удаляю нах и самоделкиных соорудивших подобный высер в ЧС.

Cuidadooooo, esta extensión registra en sus servidores todas las paginas a donde ingresamos y capturan todos los datos.

proprietary license, mile long privacy policy. not really what you want from a privacy addon. not gonna go near it myself

Contains two trackers owned by Google and Yahoo (see https://reports.exodus-privacy.eu.org/reports/178/)

There are better open-source alternatives.

Better, safer alternatives out there
