doesn't even block sites in Mozilla Firefox (for Developers) whereas in Chrome it works fine. Sad.

When update list of blocked site gone.

it blocks sites even if they are not on the list. Totally unrelated sites. Weird but it makes the add on unusable to me :/

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

Can't Unblock.

couldn't find a way to exclude sites but otherwise a fantastic app

"Access your data for all websites"
You don't need this. Used to be a good addon now my Malwarebytes is labelling it a pup and upon looking up further information online I have determined this app can get lost.

Take your spyware, data collecting and go home.

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!
