Very useful extension. Glad to have it working on Firefox Quantum.

I do have a small complaint: the settings do not seem to sync across devices. Is this true for everyone, or is there some problem in my setup?

Edit: Thanks for the reply, James. I look forward to the sync feature. And thanks for the work!

Thanks for developing this for Android!!
Also, i have a problem, there is no way to add entry with contextual menu like PC version, will you add this in the future?

Dead useful for productivity.

It is a very good add on that gives your self-control a bit of help. Obviously it's no match for a determined frickarounder, but does objectively help quite a bit.
-1 star because they took away the quick add to block set option. If I want to ADD a site to options, I have to go into options now. Also, it would be nice if it required a restart to disable this add on. As it is, it does not.

It helps me to stay productive during the day.

I once tried to block during the whole day. Now have come to model of allowing up to 15 Minutes per hour and it works wonders.
My list of sites to block is evergrowing.

Great Add-On

This saves me so much time at work, it's incredible. Since I everyday seem to forget that I shouldn't be surfing for unimportant stuff, LeechBlock is there to remind me.

Very useful for kids ..Tested and approved :`)

I'm in the process of switching from Chrome to Firefox for ethical/privacy reasons. On Chrome I really rely on an extension called Strict Workflow that combines a Pomodoro timer with website blocking, but I couldn't find a similar add-on for Firefox. Instead, I combined Leechblock's lockdown feature with a pomodoro add-on called Tomato Clock. When Tomato tells me I have a break, I just enter my password to override the lockdown for 5 minutes and get back to work. So far it's working great. Thanks guys

being able to control my spent time on social media
and the "every x hours" options is great
thank you

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!
