Doesn't block all NSFW sites, should be doing that...

ok :)
Missing option: silent blocking.
A loading of, or redirect to a specific URL should not be executed or commented by addon. Perhaps only a small drop down sign :)

Not bad to block all the stupid propaganda about the war but it doesn't prevent the sites to appear in the search engines.

It's really good. But it's not as intuitive as it could be.

Works pretty well, but after a few years of using it my list of blocked sites just DISAPPEARED. This is when I was logged in to my FF account as usual. Bizarre.

I want instant close option than minimum 1sec.

I use pages where I read headlines of articles I might click, but some pages are behind walls or I do not like - this is a nice protection. The contra is that a page opens with the restriction info, which I must close then - a 5 seconds blend in info would be more comfortable for me - luxury problem. :-)

It's nice to be able to block sites I don't want from loading, but I wish there was an option to have those sites instantly close, rather than having to wait the 1 second.

good complement, but I wish it also asked for password in the page options button when the page is locked, easy children can access there and delete the locked pages and master password. And my point of view for an easier and faster configuration would recommend making the button to save change and the one used to configure the master password more visible, personally it took me time to find these options.

Now that there is a virtual school, children should not be distracted by other pages while in class

It works well, but the settings are not friendly to users.

单击时会屏蔽根域名, 我只想屏蔽当前子域名, 希望设置成默认屏蔽当前子域名, 别误杀.

Misspoke earlier, the extension works as it says, and well. Would be nice to not be able to disable it without the password but that's likely limited in scope for an extension.
