You guys are the best! This is something I was forever looking for. Block the website, easy to use and custom messages. Just perfect!

I've used several tools for helping me focus while working. This one is by far the best I've found. It allows me to set up my limits while I'm feeling strong so that I don't cave in my moments of weakness.

Super easy to configure and the timer features are very useful. Excellent addon. Must have in the social media world

Very Good

Extremely useful for doing work. Works great against impulsive youtube searches.

It really helps with productivity. The available options are also very useful.

As a suggestion, setting Leechblock to block specific Google searches took a bit of time. Maybe some built-in tips regarding this would help future users who might encounter similar difficulties.

Cheers!

Best time saver/productivity tool for Firefox out there

I use this to block Twitter because I refuse to give the apartheid-funded jackass who owns that site and has chosen to make his mid-life crisis everybody else's problem any more traffic. Thanks, Leechblock!

this is a must-have for me. it's been a lifesaver. i have recommended it to many people over the years and included it in lectures to students.

if you find yourself accidentally or automatically navigating to certain websites, but don't want to block them completely, check out the "delay" feature -- you'll be amazed at how a delay of 2-8 seconds can rewire your brain.

Perfect, keeps me dicplined

Excellent app, I use on both desktop and mobile

Greatly helped me to focus on one site without hassle.

Highly customizable and does exactly what it says on the tin. Slight learning curve but provides deep flexibility that other blocking plugins don't have.
