the people who switch to Firefox for ad-blockers and ad-free YouTube aren't the kinds of people who are donating much to Mozilla
I went to donate to Mozilla when I switched back to it from chrome early last year. It said on their website by the donate link, which was very difficult to find, that the proceeds from those donations did not go towards firefox but towards their other projects.
I don't know if that's the case today, but there was no way to contribute to firefox directly when I sought it out, or at least not in a way I could find. Maybe it was a stipulation of the Googlegeld, idk.
They really should be copying the success of the Wikimedia Foundation and Wikipedia
Step 1: Be hilariously wealthy from prior investments and businesses
Step 2: Do a thing nobody has ever done before at a time when interest rates mean money is free
Step 3: Blind luck
I'm not sure how they're supposed to reproduce those at this point.
