Really helpful add-on, it has really improved my life.

Excellent supports all sites very motivational

very effective and useful extension.

Very capable, lots of options.

This extension is very, very, very cool

Excellent and has helped with my productivity.

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.
