Rated 5 out of 5 stars
I love this add-on because it seems a little too easy to go to Facebook during the workday and while you're trying to get other chores done. So LeechBlock makes it very easy for Facebook addicts like me from logging on to the site when the temptation hits. I also like that you can add multiple sites to the blocker; Twitter, Yahoo, Craigslist, and walmart.com have been on my list to keep me from shopping. Great add on I love it!This review is for a previous version of the add-on (0.6.3).
