Shortly after Google Chrome's Extensions gallery opened, we rounded up 18 worthy
downloads. Now that Chrome's official add-on market has matured a bit, we've dug up more
productive, annoyance-fixing, feature-adding extensions that you should consider adding to
your collection. What extensions have made their way into your must-have list, or just your
Chrome taskbar for now? Tell us, and link, your favorite finds in the comments.
