For a few years I've used FF for shit that's unimportant and Bitwarden for stuff that is, so a combination. Mainly becase I might go the entire day or three not needing banking, finance government stuff where my ID can be compromised and don't need to open BitWarden at all.
I use FF on Linux, Android and Windows when my partners Laptop has Windows issies
I use Aegis for 2FA becase its easy to do a backup and store the password for the encrypted backup in Bitwarden.
I have no idea if this is sane or efficient, its just how I do things now.
