One of the keys to the success of Firefox, the popular open-source browser produced by the Mozilla Foundation, is its extensibility. Earlier this summer, the Mozilla Foundation sponsored a contest, dubbed Extend Firefox 3, that offered prizes to the best add-ons that developers would submit. Last week, contest judges announced the winners.

If you're a Web developer, it's a pretty good bet that one of your most important tools is Firebug, an open-source debugger for HTML, CSS, JavaScript, and Ajax that works inside of the open-source Firefox Web browser. Since it was first unveiled several years ago, Firebug has taken the Web-development world by storm, revolutionizing developers' ability to modify, test, and debug Web applications. In the last month, Firebug has received hosting and development assistance from Mozilla, a change that will almost certainly benefit both the software and the community.
