Can't see my Collections

Hello, I recently changed phone and after reinstalling Firefox I realised that collections are not visible on the homepage. To be clear, I'm aware they do not sync, I added everything manually and it worked just fine, they just don't appear below the shortcuts. I saw a few other posts on the matter, some were able to fix it by toggling some secret settings (which have been changed since as far as I can tell), someone recently had them reappear on their own, but I've had no such luck.
