Simple and useful, but a few days ago, it stopped working in private windows. 5 star if this issue is fixed. (edit, this issue has been fixed)

вполне неплохо работает

Just installed and so far so good. Just what I needed.
Then I checked some negative reviews in this page and I couldn't verify that those guys maybe have some virus in their computers. Any way, I will continue using it and will post if something goes wrong.

Does what it needs to do.

Excellent. Thanks a lot Ray, nice extension.

This Firefox add-on is pretty good! Ignore those people who are saying, "It doesn't work." I used this Add-on on Firefox so I could fasten. I promised that I would quit YouTube until Lent is finished. So this really helped me keep my promise!

Much more simplier UI, than other blockers. Really nice, helpful.

好用

The extension works great! took a bit to get used to but after messing around, I was able to get the customize the rules to my need. One thing I would like is a way to block some sites all the time and some on a schedule.

Works as it should!

Works just fine for me. Simple and effective, and the "close" option is great. Leaves me staring at my desktop, wondering why I tried to open reddit for the 50th time this hour.

simplistic design. Easy to block and unblock sites.

it does its job, and does it well enough. i've been using it for over 6 months now.
