Why does Firefox mobile for iOS look different on my iPhone 13 pro max vs my wife's iPhone 12 pro max? both UTD on iOS version. I suspect that I must be missing something in settings, but cannot figure this out. See images below.

On my iPhone 13 Pro Max, the Firefox app has the nice home button, tab button, and hamburger menu button on the bottom (address bar on top both cases). On my wife's iPhone 12 Pro Max, it has the "+" for new tab, the 3 dots instead of hamburger menu, and then the tab button. I much prefer the layout on my phone, as does my wife, but I cannot figure out how to change her layout to match mine.

Any help would be much appreciated!

I have not changed any settings related to fonts in firefox (running on windows 10 desktop), but I have this issue where flag emojis are displayed as a letter code on the page itself, but still display correctly in the tab at the top. is there a known fix for this?
