Very good add-on, better than the more famous one

works in normal window, new window, privacy window. nice addon

Good. Does what it is supossed to do. Easy to use.

add-ons that must be owned in Firefox

This is the best addon to block url. Awesome and works as expected. I can add redirect pages too and it works well. :) Cheers to the developers !

leaves blacklisted pages open,should either close them or not let blocked page open. worthless.

works perfectly and is easy to use.

I just want to blocks sites that I regularly visit. I want to learn not waste my time!

I cant use it

Doesn't work - doesn't block content loaded by scripts.

I was using this to block wiki hits on my searches and it was working great, but now it seems to have turned itself off. Or more likely I did something to turn it off. (idiots use wiki)

is good if you block pages the bad is that you can enter add-ons and disable or delete it
(es buena si bloquea paginas lo malo es que pueden ingresar a complementos y desactivarlo o eliminarlo)

Doesn't work. Doesn't block sites. You add them to the list and the pop-unders keep apperaring anyway, so you add to the Blocksite list again and get the message: This is already added to the list." Really? Then why do you keep allowing it to open up again if it's already added to the list? Plus, why are you forcing me to give it a rating star by making it a 'required field'? That's cheating. You are stealing reviews. This is a negative review not a positive one. I don;t want to add a star I want to remove the stars. Stop cheating on the reviews, guys.
BEWARE: In order to post a review they force you to give them a star, which is simply cheating and lying to people. Blocksite needs to fake its ratings.

Nice and easy.
It would be nice if the settings can be protected with a password.
It is a matter of time before my kids figure out and delete the extension or remove the settings:)

stopped working. Won't let me copy and paste urls anymore.

I'm pretty happy with it, but please add the options to import/export list of blocked sites.
if you want to use the extension on another computer you have to re-type all links cause you can't even use copy/paste, this is unacceptable.
PLEASE correct the issue!

Excelente. Para o que se propõe é altamente funcional. Obrigado.

Doesn't block anything. Otherwise, nice.

Complimenti,
semplice ed efficace.

Нет экспорта\импорта списка. Значит вручную надо копировать?:)) И лучше оповещение о блокировке выдавать на заблокированной странице в центре, а не всплывающем сообщении и с пустой страницей сайта, раз вкладка открывается.

easy to use

péssimo, não facilita a operação
