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.

This extension is so annoyingly good.
I use it to
- block websites I don't want to visit
- prevent myself from endlessly browsing comment sections
- have a slight delay on websites I sometimes need to visit but often browse aimlessly
- redirect myself from newspages to my (imageless) RSS-collection that's much less inviting for timewasting
And so far every idea I had just works
Huge thanks to the dev team. Amazing work there

This is one of the best browser extensions for college students ever! If you lack the will power to close your browser and stop watching YouTube or scrolling Instagram before 3am this will fix it! It is light weight and runs great. You can even add a custom URL (Like that assignment your putting off) to reroute to if you try and open a blocked page. The military time set up is a little confusing for some people but nothing you can't Google. Overall a great add on. I will not run Firefox or Chrome without it.
