The Android version of Firefox still doesn't have working keyboard shortcuts after 13 years or a way to delete individual history items to prevent broken auto complete. The money is going into lots of other things than the browser.
I'm not sure keyboard shortcuts for a version designed to run on an OS for devices without keyboards will ever be a priority. You can use a keyboard on an Android device, but the vast, vast majority of Android devices are phones that never get used with keyboards. I don't expect there's much priority to adding that feature.
I agree that a lot of money is going to things other than the browser though.
