The commercial entity of the Mozilla Foundation has kicked off the Extend Firefox competition in an attempt to encourage developers to create Firefox extensions, little add-ons that offer functionality or other nifty features, for the 1.5 release (which is available as a release candidate).

Developers of extensions aren't doing the work for nothing, not only do users get the benefits from their work, but they can also win some great prices offered by the Mozilla Corporations and its partners, like AlienWare for an uber Gaming rig.
