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.
