As a happy FF user on Mac, Android and Windows, I'm badly missing FF add-ons for iOS (iPadOS actually) - this is due to Apple's policies on iOS prohibiting apps from downloading plugins outside of the App Store. The web without an ad-blocker and proper cookie cleanup (not to talk about FF containers) is impractical to me right now.
Maybe I (or someone) inspired by custom browser project like the OPs, will someday bundle FF with crucial add-ons for iOS and ship that through Github. It would probably need a dev account to install it in iOS/iPadOS, but it sure would be worth it. What I don't know is if regular FF add-ons (uBlock, cookie autodelete, etc.) will work on iOS FF since it runs with a bundled Safari webkit renderer, another Apple iPhone v1 2008-era-restriction for such delicate piece of hardware (weak battery, mem and cpu) that makes no sense now with powerful 2020 devices.
