used to be a great extension but they changed it and now it only blocks up to six sites so it's completely useless! Far better options out there folks!

Was great, but now you can only block 6 site with the free version. So its basically useless without paying

Used to be good, but now it's a cash grab. Avoid.

Superb blocker of inappropriate content. The best I've seen without any need for manual settings. The password lock is nice but on FireFox it still is not capable of protecting itself from someone accessing the add-ons manager or by the 'Firefox refresh' through about:support or the 'Restart with add-ons disabled' from the 'Help' dropdown in the settings. The add-on also does NOT work in private-tabs. If the function in private tabs and security can be improved, this would easily top all as a complete package and no need to look elsewhere.

used to be free , now you are limited on the number of sites you can block and once it reaches that amount even if you remove from your list it still forces you to pay

Пользовался несколько лет. Раньше у меня было заблокировано 15000 страниц. А сейчас ограничения всего 6. Советую разработчикам увеличить количество сайтов хотя бы до ста и зделать расширение более приветливым для пользователей которые никогда его не открывали. Слишком всё ограничено и навязчиво. Если бы я его первый раз открыл, то пользовался бы не долго...

As others said, you have to register. And you need to grant it access to all your web data. More importantly, how can a web browser in 2020 not be able to do natively what web browsers did 20 years ago? Blocking a website is a piece of cake, come on Mozilla!

Features that were previously there, now require registration with email. Do you seriously think I want to register in every possible firefox addon to gain basic functionality? Cancer.

PS. I read in other reviews that you dont only have to register, but also pay. You must be mentally ill if you think I will pay for this. Laughable.

I was happy with the app as it has friendly UIs. But today I'm really upset about it as it does not allow me to block more sites unless I subscribe, and in their website it is not clearly stated how many websites we can block in the free version. I tried to delete some and it still does not allow me to add new website - it is clear that it forces me to pay if I want to continue with the extension. It feels so bad and I will shift to other extensions as it does worth it if I only want to block one or more sites.

It does not completely block a website. I blocked a website with the addon and that blocked site still could leave some cookies on my browser. So, the addon still allows a blocked website to establish a connection, although a short one, still enough time to leave cookies. If you look for an extension that completely blocks any connection so a website won't find out your IP address, that one ain't doing it for you.

Can only block a couple of websites! This app is really trying to make you pay for it no point in calling it free once you put a paywall on the main thing, Its basically a trial product now.

constantly trying to upsell you to their subscription service, this extension is becoming painful to use.

as others have said the UI has been modified with a dark design pattern that makes you think you can't block sites unless you upgrade. ironically, somehow they have made this addon which is meant to block distractions, pretty distracting due to its incoherent UX.

Blocksite previously got caught out for malicious activities and acting as spyware [1]. Unistalled it today and started using LeechBlock instead, which works way faster and has better features.

Blocksite moved to a freemium model too, so everytime you open the UI it's constantly trying to get you to upgrade, pretty annoying.

Tava assistindo muito anime, vamos ver se paro agora.

Turned greedy. Bye

Uhm dudes? That some shady design decision to replace the quick-toggler (enable/disable) with the UPGRADE button to make people think they have to upgrade to enable blocking sites now. You have go into the settings to toggle it now. What a crap.
