Except you’ve actually changed nothing. Apple forces all third party browsers on their devices to use WebKit (the Safari engine) for the backend, so really all changing browsers does is give you a reskin under Apple’s thumb.
I love FireFox and I love my iPhone, but the iOS FireFox app is objectively terrible. I realize that fact is completely Apple’s fault though.

Firefox on Android sucks. I make a Google search, images show up in the results. I click an image and it doesn’t open up, just freezes the browser until I click the back button.
Is that a Firefox issue or Google making proprietary standards that only work with chromium based browsers?
I think Google is trying to be anti competitive. I have noticed similar issues when using Firefox with Google Docs.
Take a look at what a former Mozilla exec had to say on the issue: https://www.zdnet.com/article/former-mozilla-exec-google-has-sabotaged-firefox-for-years/
I recommend mull over firfox for mobile. Has many of the patches from torproject and arkenfox user.js, and it is released by the divestOS project. All id add to it is ublock origin.
