Autofill on Firefox for Android is inconsistent

I have a Galaxy S21 with Android 12. I've tried using Firefox and it's a non-starter. I couldn't even register for this community using it. Numerous other sites like AT&T don't autofill. I switched to Chrome and was able to register but could not generate a password. I had to use the Android app to generate the PW but then 1Password didn't store it. I've uninstalled 1Password and reinstalled it twice. I've turned off and on autofill numerous times. I'm losing my patience. If autofill doesn't work in any Android browser, I need to find an alternative solution.
