> They have a lot of money in the bank. Donations are a drop in the bucket What is the basis for these statements? Mozilla's budget is far less than its competitors, Google, Apple, and Microsoft; I expect they could find good uses for a little more.
They've got 1000+ employees (in 2015 at least). I don't imagine them having more money really helping anything. edit: in response to fabrice's comment about other orgs, checkout http://www.givewell.org/
I don't follow that argument; the evidence seems inconclusive. That's not a lot of people for a software company developing multiple products (and in 2015 they still were developing FirefoxOS), including one as complex and fast-moving as a major web browser, as well as furthering other missions.
Do you know how many work on Firefox, compared with Chrome, IE, and Safari? What are the budgets for the other browsers and for Firefox? That would be evidence that would be applicable.
