I left chrome and started using firefox because of this extension.

this add-on is a productivity booster!

إضافة مفيدة لفايرفوكس، باستخدامها يمكن للشخص أن يُنجي نفسه من إضاعة وقته في المواقع المختلفة دون انتباه منه

<3 Thanks for saving me from blackholes in the internet during work hours. My productivity is up again!

Thank you so much for this marvellous addon! It safed my productivity! It is the best blocker ever made, I tested a lot!

Than you for this cool add-on !

Great add on! Very useful to stay focussed on your work.

Happy it is back in the lasest Firefox version. I was wondering if it is suppossed to work in Firefox for Android as well? I tried to install the add on, and although the add on is running, the indicated websites are not blocked. Would be great to have it on Android as well :)!

Thanks!

UPDATE: Amazing, indeed it works in Android too. Love it!

Erst muss ich es versuchen

Great extension! Keeps me from wasting time.

Thank you very much. This addon is very useful.

This extension is a complete lifesaver! Thanks a lot for all the effort you have put into this.

However, I have temporarily reduced a star in the rating because I noticed that your latest update requires permission to 'Download files and read & modify my download history' and I wasn't completely sure why that was needed. Can you please shed some light on this?

EDIT: Thanks a lot for the quick reply! That commit explains the changed permissions.

Thank you very much! The extension is perfect!

Thank you, One of my prefer addons, BUT please the feature putting a difficult challenge to enter to the options is important, otherwise it is difficult not to fall into the temptation (SOLVED)

THANKS! I've been a happy user of LeechBlock for about six months, and the NG version arrived just in time for Firefox 57 to come out. James Anderson, you're making me more productive and a happier person because I'm less exposed to the never-ending flow of bad news and nonsense of mass media... the guilty, non-focused 5-minute attention span of sudden twitter feed wrath... which I now block for most of the day. Hurray! Instead I can focus on reading more indepth news at appropriate times.

The NG (NextGen) version takes advantage of WebExtension features by appropriately reporting which data it needs access to and control over. This is a huge step forwards. It also installs faster and options panel seems more responsive.

I installed it and it worked first time -- I configured it, and it triggered first time I tried visiting a blocked site... without having to restart Firefox!

A few users have started reviewing a work-in-progress and complaining about features that are being developed or have arrived shortly after. You people should participate in development on Github instead.

Thanks for updating it for Quantum! I tried a couple other focus blocker extensions and they are garbage compared to this one.

Great productivity tool! Lots of customization options without being overly complex. Open source using the WebExtensions API to support the latest versions of Firefox.
