Great! It blocks and blocks and blocks. Could (only) be better if it blocked the side-bar also!

Though I am aware of accusations of data mining against this developer, the extension is too valuable to sacrifice.

It helps me a lot with my addiction!

Works just like I hoped it would. Very simple to use and effective. I can't tell you how many times I accidentally end up going to some popular websites I blocked because they always left me in a bitter mood. This add-on helps me stay sane.

安装之后体验了戒毒生活，你能清晰的感觉到网络带来的快感和戒断时的落差。Great!

Well, a very good add-on for blocking sites you don't want to visit, even if you enter by mistake. I recommend it!

It's usefull, thanks you
