That still doesn't answer why should I donate to Mozilla the non-profit? What do they do with my donations? According to another post they don't use them to fund Firefox or presumably any project run by the corporation side.
As I see it if I wanted my donations to go to political or other activism there's more direct and better organizations to donate to with less middle management involved.
* supporting a diverse group of fellows working on key internet issues [looking at them they all focus on advocacy and social issues rather than working on things like Firefox]
* connecting open Internet leaders at events like MozFest
* publishing critical research in the Internet Health Report
* rallying citizens around advocacy issues that connect the wellbeing of the Internet directly to everyday life.
Or in other words, exactly as the HN comment said, none of it goes to corporation projects but rather privacy and social advocacy.
edit: I'm guessing the Foundation actually takes money from the Corporation to fund itself since the financial statement seems to cover both, anyone know if that's the case?
