Super configurable, developer actively fixes any bugs...

Muito boa extensão para definir o tempo limite de sites. Ela é excelente para que consigamos nos livrar de sites que estão tomando muito o nosso tempo, como as redes sociais.

Amazing add-on!

This Add-on is simply amazing!
It has helped improve my productivity immensely. Its very easy to use and also quite effective.
I use it to block all social media from my laptop during working hours.

Really helps me for blocking certain sites that I really want to quit.

Browsing can be so distracting and procrastinative, yet the makers of browsers seem not to consider this aspect at all. LeechBlock fixes this in a good way. There are extensive configuration options. I would like to see more possibilities to combine them: for example, I would like to delay pages and when they are eventually shown still apply a gray filter or blur. Even so, the add-on is great and I am very grateful to the developers.

nasty pop-up --> many pop-up blockers --> :( | LeechBlock NG --> :)

Awesome, easy to learn and customize.

Once you take the time to read the directions, it's incredibly flexible and easy to use. The best I've seen on any browser!
