Awesome, has the most options out of every app I've tried so far.

This app has helped my productivity tremendously. Works perfectly.

This addon is a life(time)-saver! Always my first install on Firefox!

Really help to avoid stupid habits like opening facebook or other pages each time when you use browse.

I tried this add-on several months (or years ?) ago.
Now it has been updated and they fixed the reason why I stopped using it : I could go in the settings and disable the lockdown in the relevant block. And I often did it. Now we can't, it appears grey when blocked, and it's perfect.
Thank you.

Just what I needed, plus more

This extension was extremely helpful with time management and helped me get into my desired university, very helpful for anyone who is easily distracted.

It is great since I can optimize so many things, and is quite simple and straightforward. But there are some settings that I don't fully understand.

sau gut.

Simple to use, offers all the features I could want, and works perfectly

Ok

Works really well and boosts my productivity

Thank you James for your marvelous brain. I just discovered this app 2 days ago and I can't believe how much it stop me from getting distracted on Youtube, Amazon.com, and just wasting time.
You're the BEST!!!

MEGA customizable blocker, but also very accessible. I've benefited a lot from this extension

Admittedly I've never gotten the overrides feature to work, but I guess that's a blessing in its own right...

(Developer's blog seems pretty cool too)
