This presence [Firefox' growing market share] brings a range of opportunities. Many of these opportunities involve working with other commercial entities. Some involve generating revenue.

The Mozilla Corporation has been created to address this. The Mozilla Corporation is a taxable entity and so is legally permitted greater freedom of action that is the Mozilla Foundation. The Mozilla Foundation will use this ability to interact with commercial entities and to generate revenue only in those cases where doing so meets the goals of the parent. In other words, its goals and mission are the same of the Mozilla Foundation, only it has greater flexibility in how to meet them. If it makes sense to generate revenue (as we currently do through search relationships) the Mozilla Corporation will look at doing so.
