Apple themselves do not allow using anything other than WebKit unless you move to the EU or Japan: https://developer.apple.com/support/alternative-browser-engi...

Firefox addons target gecko, not webkit.

What Orion's doing is horribly hacky and prone to cause issues with a multitude of addons, and of course Mozilla shouldn't bow to Apple's incredibly anti-competitive behavior.

You pay apple for a phone that can act more-or-less as a general purpose computer with apps. Apple should let you install the apps you want, and that they don't do so is insulting.

The fact that the EU and Japan ruled it illegal, and Apple responded by only changing it in those two countries instead of all countries is doubly insulting.

Until recently Apple only allowed Webkit on iOS. In the EU and Japan now they allow proprietary engines. But this means Mozilla needs to put in all the extra effort to maintain yet another branch for iOS with all the features, for an even more limited user base in those regions alone.

As always, it's Apple neutering their own platform. They don't allow a lot of things on iOS. Non-WebKit browsers is one of them (Which is asinine).

The EU forced them to allow other browser engines in their regions, but it's not global, and therefore fragmented.

what's the current excuse for buying a device which doesn't allow you to control what software you use on it?
