This is an really good app, it helps you to manage your time, without temptation for facebook or youtube etc...

Great extension!

Being able to limit my time on those wasteful websites like reddit or facebook has boosted my productivity to levels I would only have dreamed of. I do like the features like the override ability as well, as sometimes it is essential that I continue with my readings or the like. Simply incredible, one of the best productivity addons I am using now.

LeechBlock has really helped me avoid social media and concentrate on my work.

This is the most important addon available for Firefox. Thank you so much for updating it for FF57+ :) The fact that it keeps me sane on Android makes it even more amazing.

The Android version doesn't work with time limits, though. Just hard blocks. The timer sits at the maximum time and doesn't tick down.

Still a solid 5 stars <3

Great, but I wish I could get this on my phone too

This thing has led to me being more productive at night to do homework. Every night I would drown myself in YouTube videos consistently and wait until the last minute to do my HW, but now it has forced me to do so and now I get stuff done quicker.

Excellent add-on, I recommend it to anyone trying to reclaim control over their time and attention.

I love how it's fully customizable, including:
- particular times of the day when a certain group of pages should be blocked
- how long each of them can be viewed (per day / hour / whatever you like)
- whether or not a site should be hidden from sight only when loading, or also while reading passively

It also displays a tiny timer indicating how much time you have left for today on Facebook or other distractions ;)

This extension is a nice improvement from the old (non-NG) version of the plugin, which already beat the competition hands down.

The addon is a webextension version of the Leechblock addon and helps me not wasting time (apart from writing a review when I should be studying ;-)).
You can block a list of domains or load a list of domains from an url. You can configure the day(s) of the week and the hours and minutes (eg. 0700-1700).
You can block yourself from undoing these settings and even disable the addon page of Firefox (be careful, you could lock it forever) to hinder yourself from disabling the addon.

A wonderful add-on that allows you to increase your productivity by limiting your website access.

Great addon, good for blocking facebook when your getting drunk , and easy to use. Give this guy a clap or even better, a donation

Really love this add-ons, thanks LeechBlock!

I have trouble going to bed on time because I lose my sense of time when I read. Setting up a leachblock set to block everything after 10:30pm gives me the Shelling fence to go to bed.

I can limit waisted time on news and social media, and also limit my work from home

FINALLY! I was looking for a good Blocking App to restrict myself from wasting time. The only other I found - "Block Site" - is a piece of garbage that doesn't work at all how you expect it to work. This one does! Congratz!

Exactly what I was looking for, and with all the options I need

Great for homeschoolers. Keeps kids off their favorite websites until school is over.

Great add-on, lots of options and easy to set up. LOVE IT!

At the moment of writing this review (29-01-2018) it's the only reliable option available to block sites in Firefox Quantum.

Great Addon! Easy to handle and helped me lose the habit of checking pointless news every few minutes when working on challenging tasks.

This is the ONLY extension you need if you want to kick bad internet habits, quit porn, or just reclaim the time spent online. Can not thank the developers enough. Thanks Leechblock!
