Excellent Tool Rated 5 out of 5 stars

Easy to set up, easy to use. Although only an occasional problem, I use this add-on to stop unconscious procrastination. My bookmark toolbar is very easy to reflexively click. LeechBlock stops my casual browsing habits from affecting my study.

Fantastic! Rated 5 out of 5 stars

Very simple to use on first try. Very effective at blocking sites. My study schedule is very grateful, thank you!

Great add-on to stay focused Rated 5 out of 5 stars

I have become more productive at work since using Leechblock. I like being able to control how long I can visit sites, to keep my at-work web browsing to a minimum, while still accessing the websites that I need for work.

Absolutely fantastic Rated 5 out of 5 stars

Simple, hassle-free. Also provides various options to provide (or rather take away) control for website blocking. Initially time-setting can be confusing, but just remember that it works on a 24-hour schedule, aka always start with 0000 and end with 2400. FAQ really helpful.

Could not modify; had to uninstall Rated 2 out of 5 stars

Leechblock worked well initially. Then I made the mistake of checking the option to be required to enter a 32-character random access code in order to access the options field. **The problem is, even if I want to make the blocking more stringent, I still have to enter the string.** So I uninstalled and re-installed. Didn't work - string requirement still there. Once again - uninstalled, cleared cookies, re-installed. Didn't work. At this point, I have to decide that more time is being wasted trying to make Leechblock work than it would be on the sites I was blocking. Too bad, because if this bug were fixed I'd reinstall it. *Thanks for your reply. I don't want to enter a 32 digit access code (this is actual very difficult for me ) which is why I tried a reinstall. It seems reasonable to me that reinstalling any software should reset the parameters to default.

What bug?

There is no option for entering a 20-digit string. Perhaps you meant the 32-character random access code. If LB is asking for an access code it's because you selected that in the options. All you need to do is go to Options, enter the access code one time, then change the option so that no password or access code is required.

Good job man!

Keeps me on the Straight and Arrow Rated 5 out of 5 stars

Helps me stay on topic, and use time wisely. And it has way more restrictive features than I've seen other productivity software implement (even to the point where, if you aren't careful in your implementation, you can lock yourself out to the point where you have to wipe everything!).

If you want to enforce some control on your life, this is a good place to start

Fantastic blocking tool, exactly what I wanted. Rated 5 out of 5 stars

I was initially trying to find an alternative to StayFocusd for Firefox and worrying I wouldn't find a good one, but now I'm worried I won't find a good alternative to LeechBlock for Chrome.

LeechBlock is lightweight, configurable exactly in the way I want it, and really easy to use. Fantastic work, a great extension. One small feature request: Something showing time left when I visit one of the pages in the blocksets.

Vey Good Rated 5 out of 5 stars


Thank you so much Rated 5 out of 5 stars

Great addon.

Wonderful! Rated 5 out of 5 stars

I was concerned by waste of time while writing or blogging and LeechBlock is the best blocking program I've never used to prevent it. The best: its many ways of temporary block any website, allowing different time windows. No less its user friendly easyness. The best!

Gave Me My Time Back Rated 5 out of 5 stars

I've been having trouble with visiting addicting sites that consume a lot time without offering any sort of meaningful experience in return. Leechblock has made it much easier to stay on track.

Stellar! Rated 5 out of 5 stars

Works as described, haven't encountered any issues so far.

Absolutely great extension Rated 5 out of 5 stars

This extensions allows you to use it in a very tailor made way. It is great. It has been helping me a lot in order to be productive. I used to use Chrome and I switched to Firefox due to Leechblock. By that time, there was not such a great extension as leechblock for google chrome.

Fantastic add-on Rated 5 out of 5 stars

I'm using this on Ubuntu 16.04 and it works as fantastically as promised. There are several customizations available to block exactly what you want when you want. The only feature that could be added is "only let me visit this site once every x amount of time".

Works as promised Rated 5 out of 5 stars

I've used the software for a few days now. It does exactly what it is supposed to do. It's pretty barebones, but does exactly what I want it to. It's not that hard to configure once you figure out the different options there are.

Works perfectly fine Rated 4 out of 5 stars

The addon works correctly for its intended purpose and with its features like timing the usage for specific sites and other locks it's all you will need.There are some cases which are not covered for eg if you have blocked youtube and a website has embedded youtbe video then that video won't be blocked.

Leechblock Is Saving My Sanity Rated 5 out of 5 stars

This fantastic add-on is helping me stay off twitter except for 2 25-minute periods a day! I was sitting up until 2 in the AM reading my feed. Once in a while I disable it, but I find my overall patience with twitter is wearing thin. I also use it for other sites, but twitter was the reason I installed it. Can't thank you enough.
