Unintuitive interface. Either it's not possible to configure it to block a website indefinitely (as opposed to a fixed number of hours) or the UI is so unintuitive that I couldn't find that setting even after looking for several minutes.

It stopped working for some reason on my nightly AND on the normal firefox, please make it work

no sirve, y ademas hay que poner uno por uno,horarios y mas mrdas para configurar

Sadly, the parameters set for blocking times most oftentimes don't actually work, and a site will be blocked when it shouldn't be.

Doesn't work at all for me. This is the second website blocking extension that didn't work.

I'm not happy to write this review.

I always thought that Leechblock NG was perfect, but yesterday I found out that I can easily disable it by going through the add-on options. Without typing the random password.

I have tried to follow the instructions on this site https://www.proginosko.com/leechblock/faq/
But after hours I didn't solve anything.

I think I'll try "FocusMe" software.

When you can't control yourself with social media, to use this app would be helpful, if it wasn't so easy to disable in Firefox's options. You can even unblock the site at will. There is nothing an extension can do with these things, so try out an app. I'm trying FocusMe out, if I find it for free somewhere. It's not a bad extension, it's just too easy to get around it if you have no power over yourself. I hope this gets checked out and helps someone.

As soon as I install/enable this extension, Firefox slows down exponentially. If I let it run for more than a minute or two I end up locked out of my desktop environment and I'm forced to hard restart my machine.

Tested on Firefox 73.0.1, Kubuntu 18.04, KDE/Plasma 5.12.9

I followed the very clear instructions to make sure I wasn't missing anything, and I had set up the add on correctly. Still, it straight up blocked a site, although I had set it up to block me after 30 minutes. It's a very easy to use system, and I am 100% certain that I didn't tell the add on to block me- I set it up to block me after 30 min in a day. I hadn't used the website at all yet today. The grayscale filter also produced an intolerable level of lag that resolved when I removed the add-on. I installed a similar add on that was able to allow me limited access to the target website.
