I'm from China and I am always tortured by the " virus catcher" such as 金山毒霸 which colonizes my start page when I turn on my Chrome and Google. I even entered the regedit and tried to fix those browsers, but it never wored. Every time I start a browser the "duba.com" would appear instead of a neat start page with my bookmarks and often-used sites. Then I found this, which could block literally everything like a Mr.Muscle cleans a jammed toilet. It feels UNSTOPPABLE, UNBLIEVEABLE and most of all, like you are having your time of your life. THE best blocker in the world, definitely! If I figure out how to donate this in China I would certainly give hundres ( could you guys open Ali pay or We Chat pay? Or even Google Pay? which I could use to help you guys create another masterpiece like this?)
Anyway, a great add-on

Flexible and easy to setup. I love the delaying feature. It gives time to think about the next important action.

Great tool to back up the decision of focusing more during the workday. Love it!

Amazing app. Helped me block all the distracting websites and makes sure I concentrate on my work.

Tremendously useful addon. Once a week I need a no-distraction session and leechblock helped me in that.

LeechBlock is a great, simple, flexible app. I've started to become very concioius of what information (news, social media, video, etc) I'm consuming and so many "time wasting" websites become habits that are hard to break. LeechBlock really helps me recover my time an effective way.

Hello, it's been 20:08 GMT + 7, and I set all my blocked site to be unblocked at 19:00, but none of them have been unblocked. May I know what timezone this app use, so I can adapt to it. Thanks.

This is saving my writing career. Easy to set to block the sites I know I want to visit, while leaving the sites (like Google Books) that I need for research. Easy to disable (sometimes) if I want to spend my precious life energy on wasteful activities. But when it works, and I try to visit my verboten site, it shows the blocked access screen and I breath easy and refocus on work. Highly recommended.

usually great but randomly stopped working 3 days ago

Massively improves productivity

I used to have a good experience with this addon and its older pre-FF57 incarnation, but these days it paralyses Firefox as soon as I install or enable it. Does it conflict with other addons or features e.g Firefox Containers? Firefox Sync?
running on KDE Neon (=Ubuntu)

Answering the developer: yes, I have hundreds of tabs open (most are suspended). That's probably the issue then, thanks for the advice. I'll move my rating from 2 to 4 stars as the addon itself is great.

I don't know how to temporaily override blocking set.

Honestly, I created an account just to review this add-on. I know LeechBlock is very simple, yet it has greatly improved my work. I'm doing a PhD and should manage my time by my-self. Thus, I am free to procrastinate, which lead to very bad habits. I was introduced to LeechBlock by my girlfriend and it is doing an amazing job for me! I stopped thinking about procrastinating, am a more effective person in general and my work is beginning to lift off. Thanks!

I put this on for Reddit, Twitter and Youtube with 5 minute allowances every 4 hours. Works like a charm and has helped me really cut down on time spent
