"Firefox Add-ons Contributions Pilot The Firefox Add-ons community is an amazing source of creativity and innovation for Firefox users all over the world. Thousands of developers create add-ons that foreshadow the future of Web browsers, and until today, developers who wanted some sort of financial support for their development efforts had few options. Today’s release includes a pilot of a feature we’re calling “Contributions”. This pilot allows developers to request an optional dollar amount for their Firefox Add-on. Along with requesting this amount, we’re helping developers tell their stories with our new “About the Developer” pages, which explain to prospective contributors the motivations for creating an add-on and its future road map. Since contributions are completely optional, users will have ample time to evaluate an add-on to determine whether or not they want to help a developer." - Angus Burton from Bookmarklet
