totally blocks all websites.

Simple and effective, as it should be.
It will save you a lot of time!
Highly recommended

great app

Works great! Finally found what I was looking for.

Fully controllable website filter with timer. I use it to prevent myself from wasting time on FB, news channells, etc, during productive time. Emanuele

Great time saver

Best addon of its kind, almost single-handedly made me switch back to Firefox when trying other browsers

I really love this add-on. Not only functionally blocking your procrastination sites to avoid unlimited scrolling, it also shows beautiful UI of redirect page. I really love how they display the font of LeechBlock. Love it!

Does it's job, had to uninstall.

Great extension. You can defined detailed blocking rules in simple UI.

For those and abusing blocking rules:

- set up blocking rules to sites you do not want to visit
- set up "random 64 chars random password"

These way you may prefer to type it in instead of uninstalling. During typing, you may reconsider abusing your resolution.

This extension is really great. But after closing my Firefox and open it again every blocked option on it simply dissapear and LeechBlock don't block websites anymore

Simple and very effective, this extension is perfect for a better concentration at work or at home !

It allowed me to get A's on my finals, that in itself is worth 5-stars. Thank you so much!

Should trigger a refresh when the time on a page runs out! Right now it allows you to stay on the page after the timer gets to 0.

Nevermind! It works great

Works well with lots of options to customize. I like the option to show the countdown clock, too.
