Отличное расширение для ручной блокировки сайтов, но последнее обновление убило напрочь данное расширение.
Теперь при входе в настройки браузер зависает напрочь наминуту. потом отвисает. ДА и вообще браузер очень сильно тормозит когда работает blocksite.
Очень неудобно сделали контекстные меню для блокировки страниц. Раньше просто наэимаешь зхаблокировать страницу и всё. Теперь нужно лазить по контекстным меню и искать кнопку блокировки. Пока ищешь куда нажать, появляются ещё 10 рекламных окон. И пока все рекламные окна заблокирвешь пройдёт несколько часов....
Зачем вообще обновлять Данное расширение? работало нормально. Нет взяли и сделали какую то ерунду.
Ну хоть появление сообщения о установленном расширении убрали и на том спасибо... Огромный минус вообщем...

The timing feature doesn't work for me, sites remain blocked at all times even when I set a certain timeframe. Only reason I want this add-on is for the timing feature, if anyone knows one that does work please post the name of an alternative!

Looks very simple to use
Then close the browser.
Go away then come back and open browser
All the settings are gone
What's the point of that?
Renders this add-on useless
I'm sure it used to be better than this

Hope soon export feature will be fixed (not working on firefox 57 - ubuntu 16.04)

just one word:good!

Extension works perfectly and it's a good option for parental guidance. Thank you.

Easy to block sites, valid the good job it does. Still problems as disappears the list of blocked sites, and there is no way to edit an URL already stored.. we will see later on-

Easy to use

Seems to show only 1 address though 2 are set. Also, doe not work.

Was a good add-on, now it's crap that doesn't work.

best block any site which we you choose...
also have a pop up menu from where you can block site after clicking right button on that site link or button

Doesn't block links as promised; at least in my experience!

Worked fine for me. I don't know what others are talking about, maybe the problem was during update, or they're stupid.
-2 star because it blocks the site in the URL, After you've clicked on it. The website is added to firefox's history, including the back button. Which causes the back button to loop. I assume(not tested) that it would fail to block the site if it were embedded in another.
I expected this blocker to remove and/or disable links in all active html/pages I was viewing. I need a PRE-blocker, not a POST-blocker.
