I assume they do get quite a bit of money from Mozilla Foundation, which does.

I asked the Mozilla Foundation if anything from the donations goes to the browser, they said no, not a single penny.

The Foundation does not provide money to the Corporation. Look at the annual financial statements.

Do you know why that is?

Mozilla Corporation is a for-profit company. Depending on the legislation it is sometimes forbidden to take donation, or at least very difficult/limited for company.

Mozilla Foundation is the non-profit organization (and they do take donation).

They probably can take donations just fine but there is no tax deduction for the donor.

I'm going to start donating to Mozilla every month.

because otherwise users would have a saying in the direction web browsers evolve and Google would be sad

Half kidding there

So they’re accepting donations after all?
