Seems good, until you know how it handles "rollover" time. I'm tempted to give this a 1-star review, but that doesn't seem fair to me.

Edit: Nevermind, the dev doesn't care what you have to say. He'll just spit in your face if you don't like something. Don't bother.

No longer working.

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.
