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

please give feature to import and export blocked list

Now it sucks. Locksup. Can we go back?

sites in the list still appear

Very easy to use and accurate.

Excellent for preventing procrastination and other bad behavior. Helps to not waste time, while you have work to do.

Good and useful

It' simple and does what it promise very well.
I've just a suggestion..

Wouldn't be better a button outside the page to block (or toggle) a domain instead of using the context menu?
This would prevent malicious "click events" while trying to using this addon with suspicious sites.

Talking about WebExtensions:
an address or toolbar button

great add to get rid of annoying pop ups

sangat mudah sekali untuk blokir sebuah website ,contohnya youtube yang sangat menghabiskan kuota data bulanan saya. terima kasih banyak untuk pengembang :)

Hi,
Its really good so far. I request the developer to add password protection to remove blocked sites.

.. aber lässt in den aktuellen Firefox Varianten auch das Wordpress Backend einfrieren. Das hier ist eine Web Extension und sie läuft. Danke!

Didn't work at all. Tried blocking facebook.com and it wouldn't work.

Very good against all those webcrapsites which always pop up in the background, which is No 1 reason for me. All those trolls in the comments are bots from other web site blockers. Just ban/block/burn'em to >/dev/null

=D

Habe die Domain beilagen-prospekte.de erst per Kontextmenü hinzugefügt, aber die Inhalte wurden weiterhin angezeigt. Dann noch mal manuell, aber es hilft nicht.

The other Block Site is a lot better.
