能够明明白白让俺们看清楚到底是哪些流氓在拖俺们低端电脑的后腿！

Works great, don't have a page cluttered with garbage anymore ;)

Does exactly what it says: blocks ads, speeds up browsing.

I have been using Ghostery since its inception and it does an excellent job of keeping the rif-raf out of my computer.

permite no solo tiene el uso de bloquear anuncios, tambien brinda la posibilidad de ver estadistica del sitio web que visitas como su nivel de seguridad, rastreadores, rendimiento, etc. A mi parecer esta extension es sumamente necesaria para brindar una seguridad optima

Good tool. It works fine.

Helps fight teh evil. Thank you!

cool

fine when one understands the not simple interface :)
But how to back up my setting?

I feel like this is the best privacy and ad-blocking add-on for Firefox.

It works so well, that it will disable some things such as typekit on typkit.com because it uses popups. I just disable it when I use that site, but it's worth the slight inconvenience.
