Donations go to the non-profit Mozilla Foundation, not to the Mozilla Corporation, and are used for many worthy (non-Firefox) endeavors: https://www.mozilla.org/en-US/foundation/ https://www.mozilla.org/en-US/foundation/ The Corporation (which is a wholly-owned subsidiary of the Foundation i.e. only has a single shareholder, the Foundation) brings in revenue mostly through search engine deals, which is how it's able to pay staff to work on Firefox. Unsurprisingly, it's a bit confusing... I think having the ultimate owner of the Corporation and the trademarks etc. be the Foundation is a good thing, even though it makes actually funding everything appropriately a bit complex. Don't forget that Firefox is an open-source project, so contributions of time are always welcome! https://whatcanidoformozilla.org https://whatcanidoformozilla.org
