Some add-on authors request users who enjoy an add-on to contribute to its development by making a monetary contribution. These contributions go directly to the developer unless a third party is indicated, such as the non-profit Mozilla Foundation.
一些附加组件的作者希望用户在享用附加组件的同时也向附加组件捐一点款以帮助其发展。这些捐款会直接转给开发者，除非开发者明确指出了希望捐给其他单位（比如非营利性质的 Mozilla 基金会）。
