Big help Rated 4 out of 5 stars

I've got some serious procrastination and attention deficit problems, with a well-established loop of various news and forum sites, and I find this extension is a great help in building up some self-discipline. Just knowing that my page request is going to be blocked keeps me from entering the address when the urge to escape a difficult task appears. Doesn't matter that it can be circumvented fairly easily, the important thing is that it gives you the time to become aware of what you're about to do.

This review is for a previous version of the add-on (0.3.3).
