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。

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.

Works with Firefox under Mojave (Mac OS 10.14.1). Helps me with focusing by keeping me away from distractions.

it protected all bad sites, even if I had to add them myself.

Radical.
