It just randomly updated and now the websites I had blocked are now gone.

It's usefull, thanks you

alll perfect

It seems to work VERY well with ONE MAJOR EXCEPTION... yes you block the site, but you put a full screen window up bragging about it. Can't you just block it SILENTLY? (Or provide a switch for silent blocks of some known sites??)

I really needed this! Perfectly executed idea! Thank you. I have one question:

- How can I change the work time? It's stucked on 25 min.

Thank you!

does exactly what it need to do, in a relaxing way

Does exactly what I want it to. Love the whitelist feature.

Great tool when you try do some useful stuff and your facebook tab tells you "scroll me now, new post available".

useless in my firefox 64.0, is it too old?

网页被拦截后出现的界面不好看，希望像之前白白一片就很好。

分时段禁用指定网站真是太好用了，就是我需要的。我通过设置带follow和explore后缀的URL实现了不能浏览知乎时间线和发现页，但是能用知乎搜索问题的功能。既利用了知乎的学习功能，又不让无关信息浪费时间，简直完美。

It's not a site blocker, just an opened site closer. It opening every site - even of it's own blacklist (!!!) and closes it just when user discover and trying to explore new unwanted window. Useles.

The absence of an "options" button on the Firefox add ons page is absolutely maddening. I have to go on a ridiculous work-around to make changes to my blocklist. If it weren't for this, this would be a 5-star add on.

Even though I am procrastinating a little bit, it is worth it to offer some praise to this extension. Its creators did a good job in making something that's elegant and offers a tool to keep yourself accountable to your work. If you're supposed to be working, get this extension! (grateful mention to the Youtube channel "Hafu Guo" who recommended this extension). This does not hack your computer--you can turn it off--but if you install this, it is a good way to remind the weaker side of you not to procrastinate, or waste time, in the virtual void.

kudos, to the creators.
