Actually, the Mozilla Corporation, the entity that makes Firefox, is a for profit corporation that is wholly owned by the nonprofit Mozilla Foundation.

It has this weird structure because the search deal makes too much money relative to donations according to IRS nonprofit rules.

If B corps existed back when this structure was created, then they would have incorporated as that, but B corps didn’t exist then, and there’s no benefit to reincorporating as a B corp now.
