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.

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.
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.
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.
