Fantastic blocker tool. No issues whatsoever.

A bit complex but once you understand it, it's a must have

Extension cleanly and quickly does exactly what it's meant to do. Source code is also available on GitHub which is very much appreciated.

Wooaw,it's back! :) Thank you a lot.

very useful addon!

every time i set up a block and go on the blocked website my virus scan program said threat detected even tho when i used to go on those websites it did nothing so this is great :)

Leechblock saved my exams! I love the scheduling possibilty, so I dont need to think too much about activating leechblock. I would love a little plugin where you could just say "keep me from distraction for 35 minutes". Nevertheless its a great add-on

It's the best website blocker I've come across. It's fairly easy to learn how it works; comes with useful features for specific types of blocking, and very helpful with taking back my time from wasteful sites.

Thanks man. You've helped me improve my productivity and given me back my time.

This is the best website blocker! And I LOVE the keyword blocking option. Keep it up guys!

It works perfectly, and even can make it so that you can't uninstall it or change the settings while the block is active. It's really helped me focus on my work better.

Easy to set up, works great, and helps my productivity!

I was looking into multiple firefox profiles for separate bookmarks (work vs personal/entertainment), but LeechBlock is much more simple and effective. The FAQ/examples are very helpful in setting custom time periods for the lockdowns as well.

Excellent add-on to keep me productive by supporting my self-diszipline! It is easy to administer and flexible to adapt to personal requirements. Great product.

A must have addons. Helps a lot to concentrate .

Excellent add-on. I've reduced my daytime (and some night-time) social media and news viewing significantly. This is a great tool to help you stay off the computer when you need to!
