Efectivamente, te permite esconder o remover anuncios y otras cosas molestas de facebook, aunque se podria mejorar su velocidad de funcionamiento, es la mejor opción, recomendado. :D

I don't use this extension, but when I was looking for a Custom CSS extension, I saw this one listed with the unique icon, which immediately made me LOL.

So, in tribute to making my day, because of the icon of course, I posted this 5 star review.

I don't know if your extension is good, but your icon was excellent!!

Semble faire le job. Nickel !

Thank you developer for doing what needs to be done and that is giving Facebook users their Facebook's back!

Klasse

Great extention for facebook user

Enfin débarrassé de tout ce chenil. Merci !

It's great. Finally I can see my messages without annoying ads.
Thanks to the maker(s) of this great add-on... I love it :)

Geweldig, eindelijk kan ik mijn berichten weer zien zonder irritante zaken als "voorgesteld bericht" en andere onzin.
Hulde voor de maker(s) van deze fijne "add-on" ;)

Ter info: Ik werk met FF 55.0.2 (32 bits, i.v.m. de werking van sommige add-ons)...

Very nice
