I think you left out an absolutely huge question that dwarfs all of those in importance.
What other good can I do with my dollars?
That donating to Mozilla wont make it worse is such a low bar when there are kids that need malaria nets or deworming or whatnot.
If you think about the opportunity cost of donating to an organisation thats doing some things you think are really important as well as some things that you think are only kinda sorta important, when there are organisations that focus 100% on things you think are really important, then that should clear things up for you.
