I find it useful and works all the time. Also nice to see its there for mobile firefox as well.

One of the ultimate, best extensions of all time. As an addict of procrastination, my life would be more of a mess without it, and I am not exaggerating.

This module is oh-so-helpful to deal with my Twitter addiction. I don't know how I could do without it.

Simple d'utilisation sur Android. Permet de reprendre le contrôle de son temps.

Oh it works alright

Great extension for dealing with distracting sites!
Personally, it has helped me boost my productivity by being able to concentrate on work.
Please don't make it easy to uninstall this extension

It helped me so much thank you
Also for one complaining its easy to turn off, put very hard code and then you can't turn it off

I've just created a Firefox account with the only purpose of writing this five stars review. This add-on is everything you need.

Has helped me a lot in increasing my productivity and lowering my addiction, great extension.

It's great.

I use against bad habit, time consuming websites. Simple and effective! Thank you for all contributors

Great add-ons!

I was struggling with managing my time online. And this extension helps me a lot doing just that. Thank you.

An amazing tool to boost your productivity. Also simple to use =)

The user experience is technical and can be confusing at first, but it has all the features you could need.

My God, I hate the access codes so much. It's perfect, thank you so much!!
