Fantastic extension!

The best extension for productivity!! If you want to improve your life then you need to install this extension

hey , I had a problematic bug.it comes from nowhere when I open browser.leechblock developer helped me by giving a universal name for it after I sent url.still have it somewhere in is ,but the add on works great! too bad I can't get it out of my os

Truly brilliant addon with all the functionalities you would need. Would LOVE to also have this as an app on my phone, which you can sync with my desktop!

Works really great, helps me focus a lot! :)

Very good apps

Excellent propose toutes options nécessaires et imaginables ! Par exemple je peux bloquer facebook.com sauf facebook.com/events ce qui me permet d'avoir encore accès aux évènements (notamment les anniversaires) sans me faire prendre par le fils d'actualité

Straight-forward, clean, no fluff, works as intended. Makes you more productive. Hint: DO block that options page.

One of the best site blockers I've seem. I enjoy the amount of options, the way you can set up barriers for yourself (like password protecting), allowing timers for some website but not all, a time block that can be different for each website, etc.
Not only I'll continue using this extension to stop opening reddit and youtube when I should be working, but I will also set up timers so I don't waste more than 5 minutes of my free time scrolling endlessly on twitter and hackernews.
I can recommend this to almost anyone, since all features are free, easy to understand and can fit all type of user case.
Great job.

Does a good job at protecting me from some bad websites, that tend to open new pages through some evasive scripts.
