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!

Lots of functionality, intuitive to use, cleanly presented, and no bs changes in behaviour thusfar during use

This is hands down the best website blocker I have used. Similar apps are overly complicated, and do not have the functionality this one does.

Excellent and works without issues. They have thought of everything. I wanted to write my own extension to delay pages instead of blocking them, and it turns out this feature is already implemented here and works perfectly. Great!

Works like a charm. Thank you ❤️

This extension is very CPU heavy. I have about 90 tabs opened and in about:performance this extension regularly peaks to high cpu usage.

The thing is - I dont even want to do anything about my existing tabs. I just want a "new browsing" to be blocked.

EDIT: Thank you, I swear I went though the options but somehow I missed that one. It works now without CPU overhead. Fixed rating to 5*, awesome extension

Simple, powerfull

Je revis grâce à cette extension. La vie sans réseaux sociaux, c'est la vie : foncez.
