Charity Navigator information is tricky with Mozilla since it's only dealing with the Foundation, a pile of just $20 million in revenue in the last year they're covering there (closer to $30 million for the most recent available year), less than half of which was donations ("Licensing Royalties" is where the majority of the other revenue comes from... it looks like the Corporation pays the Foundation to license the Firefox trademarks and things like that, and that's basically half the Foundation's income).

The Corporation, though it's a subsidiary, takes in several hundred million a year, the lion's share being from revenue for selecting Firefox's default search engine.

Note that despite CEO Mitchell Baker's couple-million salary which has been much-bandied-about lately, Charity Navigator lists the top compensated director as Mark Surman at ~$200K. Baker runs the Corporation and chairs the board of the Foundation, but is paid only by the Corporation. The realities of Mozilla's existence don't really map cleanly to what gets reported on a Form 990 and shown by Charity Navigator.

So it's a little tough to get an accurate view of Mozilla's finances through Charity Navigator's usual information: there's lots of room for things to kind of shift around: for the Corporation to pay the Foundation for things and vice-versa.

Charity navigator has many weaknesses, but I still find it helpful. Especially with situations where there are shells or special structures. I wish they would cover stuff like the corporation. But I would never donate to an org with stats like Mozilla.

Both from bad governance perspective, and doubly so because the board knows how this appears and doesn’t care. I expect because they have stable donations and don’t rely on “retail donors” who need to use these cheap due diligence tools.
