I’ve had access to all the add-ons since a few months already using fennec and it’s been like that for years. It’s a not hard to setup but I have done it a long time ago so I don’t remember exactly how. You need to make a Firefox account. Go to your account and create a list of the addons you want to use. Copy some Kind of ID ( I think account ID) and put it somewhere in fennec. Just follow a guide.
