I have been using Ghostery for many years. One of my favorite and must have extensions.

Great extension, I use it for many years now and I still satisfied. It's one of the mandatory extension when I have to reinstall Firefox.
One disconvenient is that some pages are not working properly some time due to tracker refusal, but a few configuration solve the point.

Super module me permettant de naviguer en toute sérénité. Je recommande vivement

es la mejor extencion de todas para eliminar los anuncios de todo tipo de paginas web y sobre todo en youtube puedes disfrutar de todos tus videos sin tener que estar viendo anuncios mientras los disfrutas si quieres instalar una extencion te recomiendo este pero no solo te la instales dale sus 5 estrellas que se la merece

Ok

Great / Simple
Block Ads and Trackers

I love this adblocker. It took me a while to figure out how to get it to work with the website liveatc.net, as it was preventing me from being able to play live air traffic control feeds with default settings enabled, but I used the Restrict Site setting that now allows me to play air traffic control feeds on that website without disabling the other settings, and still blocking unwanted ads. I give this extension 5 stars and I would recommend this extension to anyone else who wants privacy while online.

Excelente plugging de uso diario. Muy útil y funcional. Recomendable.

Works good.

Well I've spent a lot of time browsing on the web. I was one of the first to use Adblock plus when it came out. Ghostery is a non invasive low cpu using miracle. I've been using this service and it is without fail the best thing you can have as a addon for your firefox. If you like privacy and no ads this is a must have
