I recently switched to iPhone from pixel and am very happy. However, I understand the need to sideload apps, haven’t watched YouTube at all on the iPhone because of the annoying ads.
I’m hoping that iOS allows installing apps from other sources soon, would also love to use the real FF.
I mean, I’ve been using uYou on iOS since I got the iPhone two years ago. It’s a bit of a pain to set up initially, but assuming you have a PC or laptop that is switched on often enough and on the same WiFi network, running iTunes and AltStore, it will auto refresh in the background.
It has sponsorblock and all that good stuff too. Normal YouTube is literally unwatchable.
