Perfect for heavy procrastinators (like me) Rated 5 out of 5 stars
I'll admit that I had my doubts about the effectiveness of this add-on, but after some use, I've found it to be one of THE most useful anti-procrastination methods that I've used. I have a tendency to lose myself in a site and forget how much time I'm actually spending, but LeechBlock never fails to drag me back to my work with a heavy "SITE BLOCKED" message.
I would like to see a sliding time window for the browsing limits, so times aren't reset on the hour (do correct me if I'm mistaken, that's what I've noticed), but depend on your last visit and whatnot. That would prevent someone spending, say, 40 minutes on a site with a 20 minute time limit just because the end of one period ended.
It would also be nice to have more customization on the "every __ ___" section. I know that sometimes I'd like to check for something every now and then, but without ending up spending too much time on that particular site. For that, I had hoped to find the option for something like, say, five minutes for every twenty minutes, but that's not really an option given the choices we have.
