Mozilla has just deleted the following:
“Does Firefox sell your personal data?”
“Nope. Never have, never will. And we protect you from many of the advertisers who do. Firefox products are designed to protect your privacy. That’s a promise. "

You can use Obtanium to pull from Github, Gitlab, and a few others, it has a search function. So you can search ‘Ironfox’ and it will find it on Gitlab, then Obtanium will ask if you want to install it.
Obtanium is available on F-Droid, or from Github…
