From what I understand, there are two arms to Mozilla... Mozilla the company (sometimes referred to as MoCo) and the Mozilla Foundation (sometimes referred to as MoFo). Again, from what I understand, MoCo is the not-for-profit company supporting the work of the Mozilla Foundation. The Foundation has an ethical mission to improve and protect the web.<p>EDIT: Here&#x27;s a quote from the Mozilla Foundation homepage (<a href="https:&#x2F;&#x2F;www.mozilla.org&#x2F;en-US&#x2F;foundation&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.mozilla.org&#x2F;en-US&#x2F;foundation&#x2F;</a>):<p>&quot;Many of Mozilla’s products are developed by the Mozilla Corporation, a wholly-owned subsidiary of the Mozilla Foundation. The Mozilla Corporation functions as a self-sustaining social enterprise — money earned through its products is reinvested into the organization.&quot;
