Very good, very helpful. But as some other users mentioned; not the most user friendly

It's very good, but its not very user friendly. However the leech block forums are very helpful to figure out how to find your solution.

Круто все!!!

I cannot focus at all on my computer without this on. Absolutely perfect prevention of distractions with TONS of customization.

one of my top add-ons for firefox. such a lifesaver. setting it up is easy, including the timeframe (to block), the condition (when the page gets blocked), making exceptions in blocking. very intuitive, very effective.

Well designed, pleasant to look at. Comfortable colours, not aggressive despite it's purpose.

Great app, exactly what I was looking for. I tried some other options available but they did not cut it when compared to LeechBlock.

Loved this
Does what it says on the can, and more!

Excelente Extensión, una maravilla.
