It's perfectly legal under US law to donate to a for-profit corporation. The donor just can't take a tax deduction for it.
And thus I guess Foundation has to do a good amount of conventional non-profitty stuff like “education and advocacy,” otherwise it would just be a flimsy facade for what’s substantially a for-profit endeavor?
Why is the browser arm organized as a for-profit at all?
This idea that Mozilla doesn't have enough money to fund Firefox is just wrong, Firefox development is perfectly sustainable, it earns more money than it spends. If you want to give money to the Mozilla Corporation instead of the foundation, you do the same thing as with any company: you purchase products from them (such as their VPN or MDN Plus, both of which are owned by the corporation).

So that they can make business deals with the likes of Google, which they wouldn't be able to do as a non-profit.
Edit: I really wish there was a single thread about Mozilla here that doesn't devolve into this being like 80% of the comments. Maybe one day.
Anyone can give Mozilla Corporation money by purchasing services.
