This is 1 of my 2 have to have add-ons. It does what it says it does. My thanks to those involved in making it and Firefox. Plus parent companys. I do not normally recommend anything, but as a I appreciate the quality of it in speed and helping protect my privacy I commend all involved. Power User. Multiple OS user.

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

Works cool for ads, but the problem arises when, after a 5-10 mins of only watching video clip, this plugin raises ram memory to 2.80GB and without it I have total RAM usage at 1.44
Thanks!

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.

Mit dem Werbeblocker bin ich zunehmend unzufrieden, er blockt immer weninger Werbung, so daß man zusätzliche Werbeblocker installieren muß.
