Changed free tier to 6 site limit for blocking. Very bad, removing and finding something better.

6 sites limit ahahahahahhahahahahahahaha

It used to be good. It no longer is.

Only blocks six sites before making you pay? Don't waste your time.

Using without paying only 6 entries possible? You're kidding me. For a thing, which is called "addon" too expensive and only in english. Sry guys - no way there.

I just uninstalled after using it successfully for a few years. It used to work great to block the occasional annoying pop up pages when it was free, but now they turned into the annoying pop up page asking for money to continue using. No thanks.

Garbage now that they changed their policy. You not only have to register (tracking you), but have to pay if you want more than six sights blocked which is a pitiful amount.

Horrible app and worse business practices. Find something else.

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.

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

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.

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.

Because the monetary program

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.

This extension collects your data.
If you are someone who cares about online privacy do not use this extension.
They were involved in a spyware campaign known as "Big Star Labs" (which is their company name) back in 2018 (search it). At that time their extensions were removed from both chrome and firefox but for some reason they were reinstated.
Remember if they did this before there is no reason they wouldn't do it now. Just look at the extension's permissions. They can collect a whole lot of data on you. I used to use this extension and really liked until now but this was a deal breaker for me.

Бесполезная игрушка.
Невозможно заблокировать рекламные домены.
Блокировать каждый рекламный банер вручную - кретинизм.
Когда-то это расширение работало, теперь оно - редкий отстой. Разработчик сосет у рекламщиков.
Не тратьте время.
