Yes, andiyou can sync between you installs.

It not perfect but it’s enough for me at least.

they discontinued the password manager they had on Android

I use it on Android Firefox every day, it syncs my passwords to all my linked firefox instances.

Oh neat. Just gpg -d HOME/.mozilla/firefox/[profile folder]/key4.db + logins.json ?

I tried bitwarden and others and finally just settled on the firefox password manager. It does everything I need.
