> I feel like Firefox might actually regain marketshare if it can ship on iOS. Firefox on Android has a decent claim to be being better than Chrome at this point (largely because you can't run extensions on Chrome).

Let's start with the facts. Firefox market share has been chronically flat with little to no change for years, as the global mobile browser market share [0] has shown even with Android having browser choice for the user.

Hence that, it also suggests that even if Apple did the same thing, it would just further cement Chrome's dominance on iOS. Firefox on mobile is shrinking into irrelevancy.
