If there is one Web addiction that the author has not been able to tame, it's collecting add-ons for Firefox (https://addons.mozilla.org). As a staple of the Web experience, browsers have come a long way. When Firefox began allowing developers to create add-on applications, browser usability was greatly improved. Add-ons make him a faster and more effective researcher, so much so that this is one addiction he is not willing to give up. Some of his favorites include: 1. Jureeka (http://jureeka.blogspot.com), 2. Book Burro (www.bookburro.org), and 3. UrlbarExt (https://addons.mozilla.org/en-US/firefox/addon/8758).
