Awesome add on and awesome dev!
Would love a feature to temporarily disable the app (for example; right click, deactivate for x minutes) since the sites I block are occasionally needed for work, and going into the add on menu is a bit tiresome.
Thanks a lot and keep up the great work!

Erst muss ich es versuchen

Great extension! Keeps me from wasting time.

Thank you very much. This addon is very useful.

Can't I register a local page to "the page to show instead of these blocked sites"?
I entered the path of the page but it didn't work...

I entered like this "file:///G:/path/file.html" but nothing happened.

I understand! Thank you for your kindness!!

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.

The new countdown timer is obnoxious and can't seem to be turned off. I don't need a countdown to the next time my filters are going to activate. I block all websites after a certain time of night and for this use case it's just an annoyance.

I've been using LeechBlock for years and I'm glad James has made it v57 compatible, but I really miss the access control tab. The lack of it really limits the functionality of the add-on. Nevertheless, this is the best program of its kind that I've ever found.

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

Absolutely the best extension of its kind. I tried a lot of alternatives while waiting for the new WebExtensions version and none of them do what I want the way this one does. Easy to use and very customizable... works great! Huge props to the dev for porting it over to the new version.

A lifesaver! Had already procrastinated my whole day on this paper. Thanks to LeechBlock I didn't also procrastinate through the night. It's great as a small little reminder to get back to work when opening up Facebook's become so instinctual. I'm glad this addon made it through the switch to WebExtensions.

Would be nice to have a quick toggle for turning on/off different block sets rather than disabling the extension or messing with the when-to-block time period/limit logic.

Works well. A bit of UI work in the settings to make it less confusing to use would be nice -- but that doesn't make this addon less useful.

Best productivity tool! Thank you so much for updating to the new extensions API; I know it's not the easiest thing.
