They forgot to mention this is only free for 3 days before you download it. There are plenty of free block site extensions out there that I would never pay for one.

Paid for the unlimited account and it won't let me add more websites. I can't even remove any website. Whole extension is bugged. I tried re-installing and it did not work.

This add-on is no good because as soon as it blocks a page, a window opens automatically and asks you to upgrade to the premium version. If an add-on advertises itself in order to earn money, then I can also push away the page to be blocked. Keep your hands off it because you are annoyed green and blue.

excellent

You can only block a defined number of websites. You must then switch to the paid version.

Dont bother with this

very useful tool

Ridiculous and misleading pricing scheme

Is just the trouble to install and remove it latter, is free for 3 days only.

На странице вместо заблокированного сайта какая то писанина. Зачем, если можно кликнуть по крестику и страница закроется? Если уж и блокировать, так что бы сайт совсем о себе не напоминал.

Why only 3 days ?

Подписочная модель - зло.
