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.

Thanks, I hate it. Saves soooo much time, but damn, is it frustrating or not...

Love it. Very good, lots of functionalities.

Works like a charm.

Been using it for a few years now. It is as good as it can get. I use it on desktop and mobile and it helps a lot to moderate my leeches. I consider it an essential add-on.

LeechBlock has helped me to be so much more productive. From blocking YouTube to other sometimes time-wasting sites, I've found myself actually doing more instead of just planning to do more.
The interface is easy-to-use, and the GUI is simple but effective. If you're hesitating to try it out, really, please don't. It will help SO much.
Thank you, LeechBlock!

(As always, this is a completely honest review from a regular human being ;)

Nice
