The problem is that every single public money drive using the "Firefox" brand since at least 2018 has been for the exclusive benefit of the Mozilla Foundation NGO, not the Mozilla Corporation entity which develops Firefox. Donations in the About screen of Firefox go to the Mozilla Foundation. The Mozilla Foundation does not appear to fund or even support anything related to Firefox:

> How will my donation be used?

> At Mozilla, our mission is to keep the Internet healthy, open, and accessible for all. The Mozilla Foundation programs are supported by grassroots donations and grants. Our grassroots donations, from supporters like you, are our most flexible source of funding. These funds directly support advocacy campaigns (i.e. asking big tech companies to protect your privacy), research and publications like the Privacy Not Included buyer's guide and Internet Health Report, and covers a portion of our annual MozFest gathering.

Do Spreadshirt sales benefit the Foundation (not Firefox), or are they revenue for the Corporation (Firefox)? I've looked around for a minute and can't tell.
