FF user since it was called the Phoenix Project.
Donating money isn't going to help them. It might help them look good to some techies that follow that information, but otherwise most wont care.
Mozilla needs to focus on other products to use in tandem w FF. Email service that is private, VPN (i think they have a partnership), Thunderbird, zoom like platform. They need office/business solutions most likely. Devtools, dev services, etc.
I'm not saying forget FF, but they can't just focus on 1 product or they are doomed.
