There are two interlinked Mozillas: the Mozilla Foundation is what you can donate to, but the Mozilla Corporation is what develops Firefox. No matter how much you donate, that money cannot (or will not) be transferred to Firefox development.

Mozilla's recent history includes privacy flub after financial management misstep, so here's a few links in no particular order of severity or chronology:

Each of these are a little rabbit hole on their own.
