Excelente não dá pra ficar sem ;D

一直用了 还可以。可以增加搜索引擎屏蔽显示某个网站的结果的功能吗

This works like a charm. Thanks for a great app to prevent me from distractions during my studies. :)

It does not block sites by URL, it actually has a totally different function from the name.

It loads the url before showing the "Restricted access" page, so it only visually blocks loading the page. I want something that never loads the page in the first place..

This is a particularly useful add-on if you are using the feature in Firefox 'DNS over HTTPS' (DoH), as DoH
bypasses your hosts file which is normally edited/used to block unwanted domains.

It is very easy to use
