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.

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.

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)

Very helpful in preventing me to open youtube unconsciously
