This is the best addon for site blocking ever. It has great features.

This addon helped me a lot to focus.

One of the best website blocking add-ons available for Firefox. Thank you !

Tried multiple other addons, enjoying now a distraction-free life

ilk dakikalardan bayıldım. evde sıkılırken çok lazım olmuştu böyle bir uygulama

Great add-on. Very easy to do initial setup, and it really does make you aware to just how much you're mindlessly clicking on social media, etc. Love that you can set a custom page (which has to be hosted on a web server, can't be a file, just threw IIS on another computer on my network), so you can do custom notes and images. Thanks for making this!

I forgot I installed this and the day after tried to use something that I blocked with it. And it worked! Super simple to set up (looks more complicated than it actually is) and really helpful for maintaining productivity.

Thank you so much!

It's given me back my life.

Before Leechblock I would get up, have coffee, and keep going on Facebook, Reddit, Digg, Quora; arguing politics and talking about whatever. I'd try to work, but I'd keep coming up with excuses to distract myself "for just a minute" with these websites. Then I'd go to bed at three in the morning and wonder why I just couldn't seem to get to work.

I told myself I could quit any time I liked. You know, like any other addict. I told myself that for fifteen years.

Within four weeks using Leechblock to get off the social media dopamine drip, I'm actually working, getting things done, and feeling good for a change. I can focus!

Thank you!

Great addon.

Definitely helps make me more productive. Blocked a bunch of social sites (and Netflix) during work hours. Great extension. Gotta get back to work now!
